 Amplitude and Intensity of Resultant Wave Calculations due to Superposition of 2 Waves

Theory and Numericals

 

Problems For Practice 1. The phase difference between two light waves reaching a point is is π / 2 What is the resultant amplitude if the individual amplitudes are 3 mm and 4 mm ? 2. Two light waves superposing at the midpoint of the screen are coming from coherent sources of light of phase difference 3 π radian. Their amplitudes are 1 cm each. What will be the resultant amplitude at the given point ? 3. Two coherent monochromatic light beams of intensities I and 41 are superposed. What will be the maximum and minimum possible intensities ?

A transverse harmonic wave on a string is described by y (x,t) =

3.0 sin (36t + 0.018x + π/4)

where x and y are in cm and t is in s. The positive direction of x is

from left to right.

(a) The wave is travelling from right to left.

(b) The speed of the wave is 20m/s.

(c) Frequency of the wave is 5.7 Hz.

(d) The least distance between two successive crests in the wave

is 2.5 cm.
