Question

following frequency of light radiation are obtained 4.2*10^8 Hz ,0.9*10^11 Hz,8.8*10^3 Hz amd 10^11 Hz. Arrange these increasing order of their wavelength

Answer 1

the increase ing order of their wavelength will be like this..

${10}^{11} < 0.9 \times {10}^{11} < 4.2 \times {10}^{8} < 8.8 \times {10}^{3}$

hope this helps you
