Rank these photons in terms of increasing energy:<br> (a) blue (λ=453nm)
alexira [117]

The increasing order of photons in terms of energy is Er < Ey < Eb

A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.

By using the formula:

E = h * ν

E = h * c / λ

h = planks constant

c = speed of light

Since h * c is constant

E is inversely proportional to wavelength  λ

For blue:

λ = 453 nm

Eb= k / 453

where k is constant

For red:

λ = 660 nm

Er = k / 660

For yellow:

λ = 595 nm

Ey = k / 595

Therefore,

The increasing order of photons in terms of energy is

Er < Ey < Eb.
