Phase of a particle gives us

Which of the following functions represent a wave 

The equation of a wave traveling in a string can be written as $$y=3 \sin\pi(100t-x)$$cm. Its wavelength is:

Three waves $$y _ { 1 } = 2 A \sin \left( \omega t - \dfrac { \pi } { 3 } \right)$$  $$y _ { 2 } = 2 A \sin \left( \omega t + \dfrac { \pi } { 3 } \right)$$ and $$y _ { 3 } = - A \sin ( \omega t )$$ interfere each other. The amplitude of the resultant wave is

If two waves of same frequency and amplitude superpose to produce resultant of the amplitude of either wave, then their phase difference is- 

The displacement of a particle executing SMH is given by $$x=0.01{\,\,}sin{\,\,}100\pi(t+0.05).$$ The time period is

The phase difference between the displacement and acceleration of particle executing S.H.M. radian is:

The two waves represented by $$y=a \sin (\omega t)$$ and $$y_2=b \cos (\omega t)$$ have a phase difference of

The displacement of a particle is given by$$x = 3 sin(5\pi t) + 4 cos 5(5 \pi t)$$ The amplitude of the particle is [MP PMT 1999]

The frequency of light ray having the wavelength $$3000\ A^o$$ is
