Answer 1

Answer:

Energy = 6.01 * 10∧-19 J

Step-by-step explanation:

Wavelength, λ = 331 nm = 3.31 * 10∧-7 m

Frequency * wavelength = C (Speed of light in vacuum), ν * λ = c

Frequency, ν = c / λ = 3 * 10∧8 / (3.31 * 10∧-7) = 9.06 * 10∧14

Now, Energy, E = hν

h = 6.63 * 10∧-34 J.s

E = 6.63 * 10∧-34 * 9.06 * 10∧14 = 6.01 * 10∧-19 J
