Answer:
The frequency of the infrared light is approximately 3.156 × 10¹⁴ Hz
Step-by-step explanation:
Given that the wavelength of infrared light, λ = 9.50 × 10⁻⁷ m, we have;
The speed of light (which is constant), c = v × λ = 299,792,458 m
Where v = The frequency of the infrared light, we have;
v = c/λ = 299,792,458/(9.50 × 10⁻⁷) ≈ 3.156 × 10¹⁴ Hz
The frequency of the infrared light = v ≈ 3.156 × 10¹⁴ Hz.
