Problem
A perfectly reflecting mirror of mass M mounted on a spring constitutes a spring-mass system of angular frequency Ω such that 4πMΩ/h = 10²⁴ m⁻² with h as Planck’s constant. N photons of wavelength λ = 8π × 10⁻⁶ m strike the mirror simultaneously at normal incidence such that the mirror gets displaced by 1 μm. If the value of N is x × 10¹², then the value of x is _____. [Consider the spring as massless]
