Answer 1

Answer #1

The energy of a radiation can be calculated using the expression

hc E

Where

h = Planck's constant

c = speed of light in m/sec

$\lambda$ = wavelength of light in m

The problem is solved in the picture attached below:

Que Given wavelength: 12.7 cm = 12.7 x 10^?m As, E. R v ho 1 Ea ho where h= Plancks -34 6.639 x 10 Jsec Constant 11 c: speed
