Calculate the wave length of the red light in air if the frequency of red light is 4.3×10^14hz. Given the velocity of light is 3×10^8m/s

λ = 6.98 × 10^-7 m

Explanation:

Using the formula; λ = v/f

Where;

λ = wavelength (m)

v = speed of light (3 × 10^8m/s)

f = frequency (Hz)

Based on the provided information in this question, the frequency (f) of red light is 4.3×10^14hz while v = 3×10^8m/s.

λ = v/f

λ = 3×10^8 ÷ 4.3×10^14

λ = 0.698 × 10^(8-14)

λ = 0.698 × 10^-6

λ = 6.98 × 10^-7 m
