## Which electromagnetic wave has the fastest speed?

Photons travel in harmonic waves at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the speed of light.

## What is the speed of an electromagnetic wave called?

Speed of Electromagnetic Waves

All electromagnetic waves travel at the same speed through empty space. That speed, called the speed of light, is about 300 million meters per second (3.0 x 108 m/s). Nothing else in the universe is known to travel this fast.

## What is the speed of electromagnetic waves in water?

The speed of an electromagnetic wave in water is 2.26×108 2.26 × 10 8 meters per second.

## What is the slowest electromagnetic wave?

Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.

## What types of waves are the fastest?

P-Waves. The P in P-waves stands for primary, because these are the fastest seismic waves and are the first to be detected once an earthquake has occurred. P-waves travel through the earth’s interior many times faster than the speed of a jet airplane, taking only a few minutes to travel across the earth.

## How do you calculate the speed of an electromagnetic wave?

The speed of any periodic wave is the product of its wavelength and frequency. v = λf. The speed of any electromagnetic waves in free space is the speed of light c = 3*108 m/s. Electromagnetic waves can have any wavelength λ or frequency f as long as λf = c.

## Which electromagnetic wave has the highest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

## Which Colour has highest frequency?

The colour with the highest frequency and highest energy is violet.

## What is the speed of light in air?

The Correct Answer is Opton 2 i.e 3 x 108 m/s. Light travels in a straight line. Light in the air is 1.0003 times slower than light in a vacuum, which slows it all the way down from 299,792,458 meters per second to 299,702,547 meters per second.

## What is the speed of a wave equation?

The period of a wave is indirectly proportional to the frequency of the wave: T=1f T = 1 f . The speed of a wave is proportional to the wavelength and indirectly proportional to the period of the wave: v=λT v = λ T . This equation can be simplified by using the relationship between frequency and period: v=λf v = λ f .
