Answer:
7.5 × 10¹⁵ Hz
Explanation:
CHECK THE COMPLETE QUESTION BELOW;
Amateur radio operators in the United States can transmit on several bands. One of those bands consists of radio waves with a wavelength near 40nm.
Calculate the frequency of these radio waves.
The frequency of these radio waves can be calculated using the expression below
ν = c/λ
Where
v = Frequency of the radio waves
c= Speed of light= 3.00 × 10⁸ m/s
λ= Wavelength= 40 nm
= 40 × 10⁻⁹ m
ν = 3× 10⁸/40 × 10⁻⁹
= 7.5 × 10¹⁵ Hz
Hence, the frequency of these radio waves is 7.5 × 10¹⁵ Hz
