To find:

Which photon has higher energy?

Calculation:

According to Planck's Equation :

 \boxed{ \bold{E =  \dfrac{hc}{ \lambda} }}

  • E is energy, 'h' is Planck's Constant, \lambda is wavelength and 'c' is Velocity of light.

So, for constant 'c' , we can say:

 \boxed{ \bold { \implies E  \propto \dfrac{1}{ \lambda} }}

  • So, higher the wavelength, lower will be energy content .

Now, convert the wavelength data in single unit:

 \rm \: 1)200 \: pm =  \dfrac{200}{100}  \times  {10}^{ - 10}  = 2 \:  {A}^{ \circ}

 \rm \: 2)2000 \:  {A}^{ \circ}

So, 2nd wave has higher wavelength, hence has lesser energy !

Photon having wavelength 200 pm has HIGHER energy as photon having 2000A°
