Answer:
Explanation:
The correct answer is right
Answer
we know,

where
E = energy
h = planks constant
λ = wavelength
from the above equation, we can see that energy is inversely proportional to wavelength.

that is why
Violet color light has low wavelength but the energy of Violet light is very high whereas red light has low energy and high wavelength.
