Two sine waves travel in the same direction in a medium. The amplitude of each wave is A and the phase difference between the two waves is 120°.

Let two A.P's have the first terms a , a' and common difference d. Given that difference between their 100th  term is 100. then a + 99d - a' - 99d = 100 ⇒...

(a) √3/√2 is the correct option

(a) Juvenile phase: It is the period of growth in an individual organism after its birth and before it reaches reproductive maturity. (b) Reproductive phase: It is the period when an individual organism...

The correct answer is (c) λ/2 EXPLANATION:  The particles at distance λ/2 have always the same displacement. So the closest zero displacement particle will be at λ/2 distance away.  

The correct answer is (b)√2a EXPLANATION:   When two waves are superimposed, the displacements of the particle due to each wave is added. Hence the resultant wave is given as  y' = a sin(⍵t-kx)...

(d) between 0 and 2A. EXPLANATION:  The amplitude of the resultant wave depends on the phase difference between the two waves. If the phase difference is zero then the resultant amplitude is...

(b) A and B move in opposite directions. (d) The displacements at A and B have equal magnitudes. EXPLANATION:   The frequencies of the particles will be the same, so the option (a) is...

The correct answer is (a) P1= P2   EXPLANATION:  Let the cross-section area = A, if the intensity of the first wave at this cross-section = I₁ and of the second wave =...

(d) the energy is redistributed and the distribution remains constant in time. EXPLANATION:  The energy at a point due to the sound wave is proportional to the square of the pressure amplitude....

(a) in vacuum (c) in a material medium EXPLANATION:  The light is an electromagnetic wave that can travel in a vacuum as well as in a transparent material medium.
