Watch Physics > Waves Videos

If the ratio of amplitude of two waves is 4 : 3. Then the ratio of maximum and minimum intensity will be

(1) 16 : 18

(2) 18 : 16

(3) 49 : 1

(4) 1 : 49

(3) $\frac{{I}_{\mathrm{max}}}{{I}_{\mathrm{min}}}={\left(\frac{\frac{{a}_{1}}{{a}_{2}}+1}{\frac{{a}_{1}}{{a}_{2}}-1}\right)}^{2}={\left(\frac{\frac{4}{3}+1}{\frac{4}{3}-1}\right)}^{2}=\frac{49}{1}$
