Question

The energy per quantum associated with light of wavelength 5890 Angstrom is

Answer 1

Answer:

3.37 *10^(-19) J

Explanation:

The energy of the quantum can be found out by Planck's equation which is

E=h*ν

where ν is the frequency of the wavelength

we know c=νλ

where c is the speed of light and λ is the wavelength of wave.

So substituting it the Energy (E) equation

we get E=h*c/λ

we have λ=5890 angstrom

λ=5890*10^(-10) m

putting the value in the equation we get

E=3.37 *10^(-19) J
