Question

Calculate the wavelength of an electromagnetic wave of frequency 10¹² Hz. Consider the speed of the wave as 3 × 10⁸ m/s.

Answer 1

Given:

Frequency of the wave (v) = 10¹² Hz

Speed of the wave (c) = 3 × 10⁸ m/s

Formula:

Wavelength (λ) = `"Speed of the wave (c)"/"Frequency (v)"`

= `(3 xx 10^8)/(10^12)`

= 3 × 10⁸⁻¹²

= 3 × 10⁻⁴ m
