 MAHARASHTRA BOARD CLASS 12 PHYSICS CHAPTER 6 SUPERPOSITION OF WAVES SOLUTIONS 


A wave of frequency 500 Hz is travelling with a speed of 350 m/s. (a) What is the phase difference between two displacements at a certain point at times 1.0 ms apart? (b) what will be the smallest distance between two points which are 45° out of phase at an instant of time? [Ans : t, 8.75 cm ]


v) The amplitude of a wave is represented by y = 0.2 sin 4ir [. —x i in SI units. 0.08 0.8 Find (a) wavelength, (b) frequency and (c) amplitude of the wave.



A wave is represented by an equation y = A sin (Bx + Ct). Given that the constants A, B and C are positive, can you tell in which direction the wave is moving?



Which of the following equations represents a wave travelling along the y-axis? (A) x = A sin (ky — cot) (B) y = A sin (kx — cot) (C) y = A sin (ky) cos(cot) (D) y = A cos (ky)sin(cot)
