समान कला (same phase) में कंपन करने वाले किसी माध्यम के किन्हीं दो निकटतम कणों के बीच की दूरी को क्या कहा जाता है?

The equation of a plane progressive wave is given by y = 0.6 sin 2π(t - x2). On reflection from a denser medium, its amplitude becomes 23 of the amplitude of the incident wave. The equation of the reflected wave is:

A transverse wave y = 2 sin(0.01x + 30t) moves on a stretched string from one end to another end in 0.5 second. If x and y are in cm and t in seconds, then the length of the string is:

The displacement y of a particle in a medium is expressed as y = 10-6 sin(100t + 20x + π4) m, where t is in seconds and x is in meters. The speed of the wave is:

Which of the following types of waves do NOT require a material medium for their propagation?

Which of the following correctly represents the relationship between frequency (f), wavelength (λ), and the speed of light (c)?

Which of the following waves do NOT require a material medium for their propagation?

The apparent change in the frequency of sound due to relative motion between the source and the observer is known as:

A progressive wave is given by the equation Y = 12 sin(5t - 4x). On this wave, what is the distance between two points that have a phase difference of 90° (π/2 radians)?
