Question

A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band.​

Answer 1

Answer:

0.015m

Explanation:

Given f =12 - 7.5= 4.5MHz =4.5*10^6Hz

c = 3*10^8m/s

f =c/lambda

Lambda =f/c = 4.5*10^6/(3*10^8)

= 4.5/300=0.015m

Wavelength band =0.015m
