. What is the speed of light in glass? Speed of light in vacuum is 
.Ans: Given refractive index of glass, $\mu=1.5$ Speed of light, $\mathrm{c}=3 \times 10^{8} \mathrm{~m} / \mathrm{s}$ Now, we have the speed of light in glass given by the relation, $$...
Ans: We know that, $I=a^{2}+b^{2}+2 a b \cos \phi$ Where, $a$ and $b$ are amplitudes of two coherent waves that are having phase difference of $\phi$. Here $a^{2}=I, b^{2}=41$ $$ \begin{array}{l}...
Ans: Some differences between interference and diffraction are the following: \begin{tabular}{|l|l|} \hline \multicolumn{1}{|c|}{ Interference } & \multicolumn{1}{c|}{ Diffraction } \\ \hline...
