Question

energy of one mole of photon of Light having wavelength
3×10^(-7)​

Answer 1

Answer:

E = 39.895 × 10 ^-10 joules

Explanation:

let E is the energy of photon , = ?

frequency  = v

wavelength , W = 3×10^-7 angestorm

planck constant , h = 6.625 × 10 ^-34 joule second

speed of light , c  = 3 × 10^8

according to the question :

E = N × h × c/W                (v = c/W)

E = 6.022 × 10^23 × 6.625 × 10^ -34 × (3 ×10^8)/(3 × 10^-7)

E = 39.895 × 10^-11 × 10 = 39.895 × 10 ^-10 joules
