Which wave would most likely be a radio wave?

question 5 options:

a. wave b

b. wave d

c. wave a

d. wave c

The correct option is (C) Wave A.

Explanation :

Radio waves are the waves in the electromagnetic spectrum having a longer wavelength and smaller frequency.

The wavelength of a wave is defined as the distance between two consecutive crests or trough.

In wave A the wavelength is maximum out of the other three waves. So, we can say that wave A shows radio waves.

Hence, the correct option is (C) " Wave A".

b.a device that inputs heat into a cool object

i think it's 35 meters
