calculate the energy of red light with a wavelength of 703.2 nm

Expert Solution

Given

Wavelength of red light = 703.2 nm

We have relation, 1 nm = 10 ^-09 m

Wavelength of red light = 703.2 nm ( 10 ^-09 m / 1 nm )

Wavelength of red light = 7.032 10 ^-07 m

We have, Energy = h C /

Where, h is a planck constant , C is velocity of light and is wavelength of light.

Energy of red light = ( 6.626 10 ^-
34 J . s ) ( 3.00 10 ⁸ m /s ) / 7.032 10 ^-07 m

Energy of red light = 2.826 10 ^-
19 J

ANSWER : Energy of red light having wavelength 703.2 nm is 2.83 10 ^-
19 J
