Answer:
f = 23.64 Hz
Explanation:
From the wave equation, the relationship between frequency and wavelength is given by;
f = cλ
Where;
λ is wavelength
c is speed of light with a constant value of 3 × 10^(8) m/s
f is frequency
We are given wavelength of 7.88 x 10^(-8) m
Thus;
f = 7.88 x 10^(-8) × 3 × 10^(8)
f = 23.64 Hz
