Light Speed

Definition of Light Speed

Light speed, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour). It is the speed at which light waves propagate through vacuum, and also the upper limit for the speed at which any form of matter or energy can travel through space. Light speed is an essential parameter in the theories of relativity and electromagnetism, and has relevance beyond the context of light and electromagnetic waves.

How to Convert Light Speed

To convert light speed to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert light speed to kilometers per hour, we need to multiply by 3,600, since there are 3,600 seconds in one hour. To convert light speed to miles per hour, we need to multiply by 2.2369362920544, since there are 2.2369362920544 miles in one kilometer.

Where Light Speed Is Used

Light speed is used in various fields of science and technology where the properties and behavior of light and electromagnetic waves are studied or applied. For example:

• In astronomy and cosmology, light speed is used to measure astronomical distances and time scales, such as light-years and parsecs. It also determines the observable size and age of the universe and the effects of gravity on light such as gravitational lensing and gravitational redshift.
• In physics and engineering, light speed is used to calculate the energy and momentum of particles and fields using the famous equation E = mc2. It also sets the limit for causality and information transfer in physical systems.
• In communication and navigation, light speed is used to determine the delay and bandwidth of signals transmitted through various media such as optical fibers or radio waves. It also affects the accuracy and precision of measurements based on time-of-flight or Doppler effect methods.

History of Light Speed

The concept of light speed has a long history that spans across different cultures and disciplines. Some of the milestones in its development are:

• In ancient times, many philosophers and scientists assumed that light traveled instantaneously or infinitely fast.
• In the late 17th century, Danish astronomer Ole Romer was the first to demonstrate that light had a finite speed by observing the apparent motion of Jupiter’s moon Io. He estimated that light took about 22 minutes to cross the diameter of Earth’s orbit.
• In the early 18th century, English astronomer James Bradley discovered the aberration of starlight caused by Earth’s motion around the Sun. He used this phenomenon to calculate that light traveled about 10 thousand times faster than Earth’s orbital speed.
• In the late 19th century, French physicist Hippolyte Fizeau and American physicist Albert Michelson conducted various experiments using rotating mirrors or interferometers to measure the speed of light more accurately in air or vacuum.
• In the early 20th century, German-born physicist Albert Einstein proposed the special theory of relativity, which postulated that light speed was constant and independent of the motion of the source or the observer. He also showed that light speed was the maximum speed for any form of matter or energy in the universe.
• In the late 20th century, various methods and standards were developed to define and measure light speed more precisely and consistently. In 1983, the International System of Units (SI) adopted the exact value of 299,792,458 metres per second as the definition of light speed in vacuum.

Meters per minute: A unit of speed

Meters per minute (m/min) is a unit of speed or velocity in the International System of Units (SI). It measures how fast an object is moving by calculating the distance traveled in meters divided by the time taken in minutes. For example, if a car travels 600 meters in 10 minutes, its speed is 60 m/min.

How to convert meters per minute

Meters per minute can be converted to other units of speed or velocity by using simple conversion factors. Here are some common units and their conversion factors:

• Meters per second (m/s): To convert from m/min to m/s, divide by 60. To convert from m/s to m/min, multiply by 60. For example, 1 m/min is equal to 0.0166667 m/s, and 10 m/s is equal to 600 m/min.
• Kilometers per hour (km/h): To convert from m/min to km/h, multiply by 0.06. To convert from km/h to m/min, divide by 0.06. For example, 1 m/min is equal to 0.06 km/h, and 50 km/h is equal to 833.333 m/min.
• Miles per hour (mph): To convert from m/min to mph, multiply by 0.0372823. To convert from mph to m/min, divide by 0.0372823. For example, 1 m/min is equal to 0.0372823 mph, and 30 mph is equal to 804.672 m/min.
• Knots (kn): To convert from m/min to kn, multiply by 0.0323974. To convert from kn to m/min, divide by 0.0323974. For example, 1 m/min is equal to 0.0323974 kn, and 15 kn is equal to 462.963 m/min.
• Feet per minute (ft/min): To convert from m/min to ft/min, multiply by 3.2808399. To convert from ft/min to m/min, divide by 3.2808399. For example,1 m/min is equal to 3.2808399 ft/min, and 10 ft/min is equal to 3.048 m/min.
• Inches per minute (in/min): To convert from m/min to in/min, multiply by 39.3700787. To convert from in/min to m/min, divide by 39.3700787. For example,1 m/min is equal to 39.3700787 in/min, and 20 in/min is equal to 0.508 m/min.

Where meters per minute are used

Meters per minute are mainly used in engineering and manufacturing to measure the speed or velocity of machines and processes.

For example, the cutting speed of a lathe or a milling machine is often given in meters per minute, which indicates how fast the tool moves relative to the workpiece.

The conveyor belt speed of a production line is often given in meters per minute, which indicates how fast the products move along the belt.

The airspeed of a glider or a balloon is often given in meters per minute, which indicates how fast the aircraft ascends or descends.

Definition of meters per minute

According to the SI definition, one meter per minute is the speed of a body that covers a distance of one meter in a time of one minute.

Mathematically, it can be expressed as:

v = s / t

where v is the speed or velocity in meters per minute, s is the distance traveled in meters, and t is the time taken in minutes.

History of meters per minute

The concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc.

The meter was originally derived from the French meter which was defined as one ten-millionth of the distance from the equator to the North Pole.

The minute was originally derived from the Babylonian sexagesimal system which divided an hour into sixty minutes.

The combination of these two units resulted in the meter per minute as a unit of speed or velocity.

The meter per minute was officially adopted as part of the SI system in 1960.
