The energy of a photo having a wavelength of 10
-10m is
(h= 6.63 x 10
-34Js, c =3.0 x 10
8ms
-1)
-
A.
2.0 x 10 -15J
-
B.
1.7 x 10 -13J
-
C.
2.0 x 10 -12J
-
D.
1.7 x 10 -12J
Correct Answer: Option A
Explanation
E = \(\frac{hc}{\lambda}\)
E = \(\frac{6.63 \times 10^{-34} \times 3 \times 10^18}{10^{-10}}\)
E = 2 x 10
-15J
