Frequency is defined as repetitive occurrences per unit of time. The frequency of a 6.43 x 10⁻⁵ m wave is 4.67 × 10 ¹³ hertz.
Frequency is given as the ratio of the wave speed (c) to the wavelength (λ).
υ = c ÷ λ
Given,
Speed of light (c) = 3.00 x 10⁸ m/s
Wavelength (λ) = 6.43 x 10⁻⁵ m
Substituting the values above,
υ = 3.00 x 10⁸m/s ÷ 6.43 x 10⁻⁵ m
= 4.67 × 10 ¹³ per sec
Therefore, 4.67 × 10 ¹³ Hz is the frequency.
