Question

the speed of light in air is 3.00 x10^8 m/s. if a light wave has a wavelength of 5.80 x10^-7 m, what is its frequency?

How r u??❤️

Here's ur answer

Speed = v = 3×10⁸ m/s

Wavelength = λ = 5.8×10⁻⁷ m

Frequency = f = ?

We know that,

v = fλ

Hence,

f = v/λ

f = 3×10⁸ / 5.8×10⁻⁷

f = 0.517×10⁸⁺⁷

f = 5.17×10¹⁴ Hz
