# Question: A photon of wavelength 6000Å has an energy E. The wavelength of the photon of light which corresponds to an energy equal to 2E is

A photon of wavelength 6000 Å has an energy E. The wavelength of the photon of light which corresponds to an energy equal to 2E is

Option 2) 3000 Å (Correct)

• Option 1) 300 Å
• Option 2) 3000 Å
• Option 3) 30 Å
• Option 4) 3 Å

As we all knows that,

The energy (E) of a quantum of radiation –

Where h is plank’s constant and  is frequency, and

where frequency is (,pronounced as nu), wavelength is (λ) and velocity of light is(c)

We also know,

E= energy of a quantum of radiation

h=plank’s constant
