Expert Answer:

Given:
 
Wavelengths of photons A and B are
 
λ1 = 100 straight A with degree on top
λ2 = 1000 straight A with degree on top
 
The energy of photon is given by,
 
 
straight E space equals hc over straight lambda

straight E subscript 1 over straight E subscript 2 space equals space straight lambda subscript 2 over straight lambda subscript 1

straight E subscript 1 over straight E subscript 2 space equals 1000 over 100

straight E subscript 1 over straight E subscript 2 space equals 10 over 1

straight E subscript 1 colon space straight E subscript 2 space equals space 10 colon 1
 
The ratio of the enegries of photons is 10:1
