A boat at anchor is rocked by waves whose crests are 100m apart and velocity is 25m/s. The boat bounces up once in every : A boat at anchor is rocked by waves whose crests are 100m apart and velocity is 25m/s. The boat bounces up once in every : October 28, 2020 Category: AIIMS [...]

An earthquake generates both transverse (S) and longitudinal (P) sound waves in the earth. The speed of S waves is about 4.5 km/s and that of P waves about 8.0 km/s. A seismograph records P and S waves from an earthquake. The first P wave arrives 4.0min. before the first S wave. The epicenter of [...]

The velocities of sound at the same temperature in two monoatomic gases of densities p1 and p2 are v1 and v2 ​respectively. If p1/p2 ​ = 4, then the value of v1/v2 is The velocities of sound at the same temperature in two monoatomic gases of densities p1 and p2 are v1 and v2 ​respectively. [...]

A string in a musical instrument is 50cm long and its fundamental frequency is 800Hz. If a frequency of 1000Hz is to be produced, then required length of string is A string in a musical instrument is 50cm long and its fundamental frequency is 800Hz. If a frequency of 1000Hz is to be produced then [...]

A source of frequency 240 Hz is moving towards an observer with a velocity of 20 m/s. The observer is now moving towards the source with a velocity of 20 m/s. Apparent frequency heard by observer, if velocity of sound is 340 m/s. is A source of frequency 240 Hz is moving towards an observer [...]

A transverse stationary wave passes through a string with the equation y = 10 sin pie(0.02x – 2.00t) where x is in meters and t in seconds. The maximum velocity of the particles in wave motion is A transverse stationary wave passes through a string with the equation y = 10 sin pie(0.02x - 2.00t) [...]

Two coherent monochromatic light beams of amplitude 3 and 5 units are superposed. The maximum and minimum possible intensities in the resulting beams are in the ratio Two coherent monochromatic light beams of amplitude 3 and 5 units are superposed.

In Young’s experiment, the monochromatic light is used to illuminate two slits S1 and S2 as shown. Interference fringes are observed on a screen placed in front of the slits. Now if a thin glass plate is placed normally in the path of beam coming from the slit S1, then Greater accuracy in the determination [...]
