Question

Be sure to answer all parts. An FM station broadcasts classical music at 105.3 MHz (megahertz, or 10 m, nm, and A) of these radio waves. Hz). Find the wavelength (in (select) x 10 (Enter your answer in scientific notation.) nm x 10 (select) A (Enter your answer in scientific notation.)

Answer 1

1)
a)

Given:
f = 105.3 MHZ
= 105.3*10^6 Hz
= 1.053*10^8 s-1

use:
lambda = c/f
=(3.0*10^8 m/s)/(1.053*10^8 s-1)
= 2.85 m
Answer: 2.85 m

b)
lambda = 2.85 m
= 2.85*10^9 nm
Answer: 2.85*10^9 nm

c)
lambda = 2.85 m
= 2.85*10^10 Ao
Answer: 2.85*10^10 Ao
