Question

wane number ( (5)=frac{1}{lambda} )
( frac{frac{G}{Q / 2}=frac{lambda_{1}}{lambda_{2}}}{frac{lambda_{1}}{1 / lambda_{2}}}=frac{2}{3} )
( frac{varepsilon_{1}}{varepsilon_{2}}=frac{frac{h_{1}}{lambda_{1}}}{frac{x_{1}}{lambda_{2}}}=frac{lambda_{2}}{lambda_{1}}=frac{2}{3} )

# Two electromagnetic radiations have wave numbers in the ratio 2:3. Their energies per quanta WII be in the ratio A) 3:2 (B) 9:4 (C) 4:9 (D) 2:3
