Respuesta :
The frequency of the wave assuming it is light having compete distance as 4.17×10^7 m is 1.44×10^15 Hz
Wavelength:- It is defined as the distance between the two Consecutive Crest or trough. OR distance travelled by the wave to Complete one Complete Cycle.
The distance for completing two cycle is 4.17×10^7 m
so 2λ=4.17×10^7m
λ=2.085×10^-7m
Also f=c/λ
f=3×10^8/2.085×10^-7
f=1.44×10^15 Hz
- A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles is wavelength.
- The number of cycles or vibrations that a body in periodic motion experiences during one unit of time, as well as the number of waves that pass a given point in a unit of time is frequency.
