Answer:
Step-by-step explanation:
v = f λ,
Where V = velocity, f = frequency and λ = wavelength
1.) What is the wavelength of an electromagneticwave with a frequency of 145,000 Hz?
λ = v/f
Electromagnetic waves have a velocity of 3.0 * 10^8m/s
λ = 300000000/145000
λ = 2,068.97m
2.) What is the wavelength of an electromagnetic wave with a frequency of 165,000 Hz?
λ = v/f
λ = 300000000/165000
λ = 1,818.18m
3.) An electromagnetic wave has a wavelength of0.65 km. What is its frequency?
f = v/λ
f = 300000000/650
f = 461,538.46Hz
4.) An electromagnetic wave has a wavelength of0.45 km. What is its frequency?
f = v/λ
f = 300000000/450
f = 666,666.67Hz
5.) What is the wavelength of an electromagneticwave with a frequency of 225,000 Hz?
λ = v/f
λ = 300000000/225000
λ = 1,333.33m
