If two light waves of same amplitude 'a' trvaelling thrugh a mdedium arrive t a point in same pahses then the resultant amplitude r at that points is

If two light waves each of amplitude a travelling a travelling through a medium arrive at a point in opposite phase then the resultant amplitude R at that points is

Two waves of amplitudes 3mm and 2 mm reach a point in the same phase. What is the resultant amplitude ?

Two waves of amplitude 5 mm and 7 mm reach a point in opposite phase. What is the resultant amplitude ?

Two waves pf amplitude 3 nm and 5 nm reach a point in opposite phases. What is the resultant amplitude ?

If two waves of same amplitude produce a resultant wave of same amplitude a phase difference between the two is

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Assertion: If two waves of same amplitude produce a resultant wave of same amplitude,then the phase difference between them will be 120 ^(@) Reason: The resultant amplitude of two waves is equal to vector sum of amplitudes treated as vectors
