A wave traveling in a medium produces changes in pressure in the medium. The wave must be |

A) Transverse | B) Longitudinal | C) Stationary | D) None of these |

Particles A and B separated by 0.25 m differ in phase by π/4 and their state of vibration of A is same as that of B after a time of 0.025 s. The velocity of the wave is |

A) 80 m/s | B) 160 m/s | C) 320 m/s | D) 40 m/s |

A wave is represented by the equation y = 0.05 sin [0.05x - 0.4t]. This represents a wave moving with a velocity of (y is in m and t is in s). |

A) 10 m/s | B) 20 m/s | C) 5 m/s | D) 8 m/s |

A wave traveling in a medium produces compressions and rarefactions at a given place. If the compressions and rarefactions have a time lag of 0.05 s and if successive compressions are separated by 0.005 m the velocity of the waves is |

A) 0.05 m/s | B) 0.1 m/s | C) 1 m/s | D) 0.5 m/s |

The equation of a wave is $$y = 1 / {(4x - 2t +5)}^2$$ with x in m and t is in s. The velocity of the wave is |
