The correct option is B B has greater energy than A-x3BB-A-0-7-xD7-10-x2212-6m-x3BB-B-0-3-xD7-10-x2212-1mE-hc-x3BB-x3BB-A-gt-x3BB-BHence- E-A -lt- E-B

Two different sources of light A and B have wavelength 0.7μm and 0.3μm respectively. Then which of the following statement is true.A has greater energy than BB has greater energy than ABoth has equal energyNone of the above

The correct option is B B has greater energy than AλA=0.7×10−6m,λB=0.3×10−1mE=hcλλA>λBHence, E_A < E_B

Two different sources of light A and B have wavelength $0.7 μ m$ and $0.3 μ m$ respectively. Then which of the following statement is true.
A has greater energy than B
B has greater energy than A
Both has equal energy
None of the above

The correct option is B B has greater energy than A
$λ_{A} = 0.7 \times 10^{- 6} m$ ,
$λ_{B} = 0.3 \times 10^{- 1} m$
$E = \frac{h c}{λ}$
$λ_{A} > λ_{B}$
Hence, E_A < E_B
