The energy of the photon having a wavelength 570 nm is calculated
3.47 x 10⁻¹⁹ J.
E = hν ...1.
where,
E = Energy of photon
h = planck's constant
ν = the frequency of the photon
ν = c/λ ....2.
where
c = speed of light
λ = wavelength
using value of equation 2 in 1 we get :
E = h x ( c/λ )
where
h = 6.6 x 10⁻³⁴ Js
c = 3 x 10⁸ m/s
λ = 570 x 10⁻⁹m
To calculate energy put values in above equation :
E = (6.6 x 10⁻³⁴ x 3 x 10⁸ )/ 570 x 10⁻⁹
E = 3.47 x 10⁻¹⁹ J
The energy of the photon having a wavelength 570 nm is calculated
3.47 x 10⁻¹⁹ J.
