Question:medium

A wave y=a(ω t-kx) on a string meets with another wave producing a node at x=0. Then the equation of the unknown wave is

Show Hint

Nodes are formed due to complete destructive interference.

Updated On: Mar 18, 2026

y=a(ω t+kx)
y=-a(ω t+kx)
y=a(ω t-kx)
y=-a(ω t-kx)

A thin transparent film with refractive index 1.4 is held on a circular ring of radius 1.8 cm. The fluid in the film evaporates such that transmission through the film at wavelength 560 nm goes to a minimum every 12 seconds. Assuming that the film is flat on its two sides, the rate of evaporation is:

Assertion (A): When two waves of equal amplitude and a phase difference of \( \frac{\pi}{2} \) interfere, the resulting intensity is equal to the intensity of one wave. Reason (R): In interference, the resultant intensity is always the sum of individual intensities if the phase difference is non-zero.
