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)
(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
