Answer:
The wavelength of wave is 1.2×10³ m.
Step-by-step explanation:
Given data:
Frequency of wave = 250,000 Hz
wavelength of wave = ?
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
speed of light = 3×10⁸ m/s
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
λ = 3×10⁸ m/s / 250,000 Hz
Hz = s⁻¹
λ = 1.2×10³ m
The wavelength of wave is 1.2×10³ m.
