Physics - Current Electricity Question with Solution | TestHub

Four independent waves are represented by equations (1) ${\mathrm{X}}_1={\mathrm{a}}_1\sin \omega \mathrm{t}$ (3) ${\mathrm{X}}_2={\mathrm{a}}_2\sin 2\omega \mathrm{t}$ (2) ${\mathrm{X}}_3={\mathrm{a}}_1\sin {\omega }_1\mathrm{t}$ (4) ${\mathrm{X}}_4={\mathrm{a}}_1\sin (\omega \mathrm{t}+\delta )$ Interference is possible between waves represented by equations
