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 ?
