Question

the energy in joules corresponding to light of wavelength 45 NM is​

Answer 1

Explanation:

Energy = h(c/y)

Y = Wavelength

C = Speed of light

h = planks constant

Convert the wavelength to m:

45 × 10⁻⁹m

Doing substitution :

E = 6.63 × 10⁻³⁴ × ( 3 × 10⁸ ÷ 4.5 × 10⁻⁸) = 4.42 × 10⁻¹⁸ Joules
