I WILL GIVE YOU BRAINLEST

Some people think a deep tan is beautiful, but it is really the body's way of trying to protect itself from the damaging effects of the sun's radiation. Fill in the remaining parts of the table below to compare an ultraviolet photon with a photon in the visible range. (12 points)

Answer:

Visible photon

λ = 649 nm

E = 3.061 * 10^ - 23 J

B) ultraviolet photon:

γ  = 8.57 * 10^ 14 s^-1

E = 5.678 * 10^ -19 J

Explanation

1) Data:

A) visible photon

ν = 4.62 * 10 ^ 14 Hz
λ = ?
E = ?

B) Ultraviolet photon

λ = 350 nm = 350 * 10^ -9 m
ν = ?
E = ?

2) Formulae:

frequency: ν
wavelength: λ
speed of ligth: c
energy: E
h: Planck constant = 6.626 * 10^ -34 J.s

ν = c / λ
λ = c / ν
E = hν

3) Solution:

Visible photon

λ = c / ν = 3.00 * 10^ 8 m/s / 4.62 * 10 ^ 14 s^-1 = 6.49 * 10^ - 7 m = 649 nm

E = hν = 6.626 * 10 ^ - 34 J.s * 4.62 * 10 ^ 14 s^-1 = 30.61 * 10^ - 24 J = 3.061 * 10^ - 23J

Ultraviolet photon:

γ = c / λ = 3.00 * 10^ 8 m/s / (350 * 10^ -9m) = 8.57 * 10^ 14 s^-1

E = hν = h = 6.626 * 10 ^ -34J.s * 8.57 * 10^ 14 s^-1 = 5.678 * 10^ -19 J
