Calculate the ratio of the intensities of the two waves, if amplitude of first beam of light is 1.5 times the amplitude of second beam of light.
a1 = 1.5 a2 To find: \(\frac{I_1}{I-2}\) Formula: I ∝ a2 Calculation: From formula, \(\frac{I_1}{I_2}=(\frac{a_1}{a_2})^2=(\frac{1.5_{a_2}}{a_2})^2\) = (1.5)2 = 2.25
