As the reference height is at B, so above that reference height is considered positive, and below the reference height it is considered negative. Hence the height-time graph is as such. Consider a vertical oscillating object, similar to the simple pendulum, the middle is the fastest.

Answer: Option A Once the water wave is produced, frequency of the wave remains constant even when it travels from deep to shallow or...

Answer: Option B Refer to the video explanation

Answer: Option B Wavefront is an imaginary line that joins all identical adjacent points that are in phase. So if you assume the circular...

Once the wave is produced, the frequency remains constant. Hence speed V of the wave is directly proportional to the wavelength of the...

Transverse waves are waves in which travel perpendicular to the direction of vibration of particles.

Answer: Option D

Though slinky coil is commonly used to demonstrate transverse and longitudinal waves, you must not quote it as an example for either of...

Wavefront is an imaginary line which joins all identical adjacent points (e.g. crests) in phase . Note that the distance between two...

Instead of imaging how the particles will move and guess their motion, there is a technique which can help you to determine that. In...

In this this question, the displacement-time graphs are given, which are different from displacement-distance graphs. In the...

When an object is oscillating or vibrating in a wave motion , the speed of the object varies along the path. In this video, there are...

Transverse waves  are waves in which the  direction of the wave  is  perpendicular  to the direction of the vibration . e.g Light, water,...
