Corrected question: The wavelength of light beam A is twice the wavelength of light beam B. The energy of a photon in beam A is:
Answer:
B
Explanation:
Energy = hc/λ
λ(A) =2λ(B)...................equation 1
We will solve for the ratio of energy of A to energy of B.which is
[tex]\frac{E_{A} }{E_{B} }[/tex]
=(hc/λA) ÷ (hc/λB)
referring to equation 1 we have
=(hc/2λB) ÷ (hc/λB)
=hc/2λB) × (λB/hc)
= λB/2λB
[tex]\frac{E_{A} }{E_{B} }[/tex]=1/2
[tex]{E_{A} = \frac{1}{2} E_{B}[/tex]
The energy of A is half of B
