Question

Two harmonic oscillations at right angles to each other with phase difference δ

Superimpose each other. Which of the following statements are correct for the resultant motion of the particle?

 (a)  at δ = 3π/2 ,  the resulting motion is left handed elliptically linearly polarized vibration

(b)  at δ = 2π,  the resulting motion is linearly polarized vibration

(c)  at δ = π/2 and A₁ =  A₂ the resulting motion is linearly polarized vibration

(c)  at δ = 3π/4 and A₁ =  A₂ the resulting motion is linearly polarized vibration 

Answer 1

Correct option (a) and (b) 

Explanation:

This is equation of circle but motion is clockwise. Wrong option (d) at δ = 3π/4, The resulting equation represent general ellipse and not linearly polarized.
