Two waves of amplitude

5 \mathrm{~mm}

and

7 \mathrm{~mm}

reach a point in opposite phase. The resultant amplitude is

View answer and explanation

Correct option: C

2 \mathrm{~mm}

Option C (2 mm) is correct because when waves are in opposite phase, the resultant amplitude is the difference between the individual amplitudes.

H-polaroid is prepared by Evidence for the wave nature of light cannot be obtained from Which radiation in sunlight, causes heating effect In the propagation of light waves, the angle between the direction of vibration and plane of polarization is In Young’s experiment, one slit is covered with a blue filter and the other (slit) with a yellow filter. Then the interference pattern Four independent light waves are expressed as

\mathrm{y}_1=\mathrm{a}_1 \sin \omega \mathrm{t}, \mathrm{y}_2=\mathrm{a}_2 \sin \omega \mathrm{t}, \mathrm{y}_3=\mathrm{a}_3 \cos \omega \mathrm{t}

\mathrm{y}_4=\mathrm{a}_4 \sin (\omega \mathrm{t}+\pi / 3)

. The interference is possible between
