The energy of a photo having a wavelength of 10... - JAMB Physics 2013 Question
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 option: a
E = \(\frac{hc}{\lambda}\)
E = \(\frac{6.63 \times 10^{-34} \times 3 \times 10^18}{10^{-10}}\)
E = 2 x 10-15J
E = \(\frac{6.63 \times 10^{-34} \times 3 \times 10^18}{10^{-10}}\)
E = 2 x 10-15J
