Question

Suppose a sound wave and electromagnetic wave have the same frequency which one will have a longer wavelength and why

Answer 1

Answer:

Electromagnetic waves are much faster than sound waves and If the Velocity of the wave goes up and the frequency is constant, the wavelength also goes up also. So Electromagnetic waves have the longer wavelength.

Explanation:

Answer 2

Answer:

Electromagnetic wave

Explanation:

This wave (which is a light wave), has a greater velocity and since wavelength = velocity/frequency (derived from velocity = frequency*wavelength), the greater the velocity and/or lower the frequency, the greater the wavelength. I hope this helped! :)

Note: Since both waves have the same frequency, the velocity is the deciding factor
