Respuesta :

The frequency of radio waves at the two stations are:

1. WIL-92.3 : Frequency = 92.3 MHz (mega hertz)

2. KSHE-94.7 : Frequency = 94.7 MHz

The wavelength (λ) and frequency (ν) are related as:

ν = c/λ ------(1)

Energy (E), frequency (ν) and wavelength (λ) are related as:

E = hν -----(2)

(or)

E = hc/λ ----(3)

A) Based on equation (2), higher the frequency higher is the energy. Therefore, station KSHE broadcasts waves with higher energy

B) Based on equation (1), higher the frequency lower will be the wavelength. Station KSHE will broadcast waves with shorter wavelength

C) KSHE will broadcast waves with higher frequency
