Doppler effect is the apparent change in the frequency of waves due to the relative motion between the source of the sound and the observer. We... View Article
Stress does not depend on Young’s modulus in the elastic region. Hooke’s law states that stress is directly proportional to the strain within the... View Article
Consider a collision between object A and object B. For such collision, the force between the objects is equal in magnitude and opposite in... View Article
The mesosphere is the layer of atmosphere that lies above the stratosphere. Mesosphere is the coldest part of the atmosphere. Not much has been... View Article
When you increase the frequency of a sound wave, the sound waves get compressed and we hear the sound at a faster rate. The pitch of the sound... View Article
When the refraction of light occurs, the incident light rays bend. The refracted light ray either bend towards the normal or away from the... View Article
Huygens principle was proposed by Christiaan Huygens In 1678. The principle states that “every point on a wavefront is in itself the source of... View Article
Diffraction is the ability of the waves to bend around small obstacles. Sound waves have the ability to bend around objects. Suppose there is a... View Article
Zener diodes are made by heavily doped n-type and p-type semiconductors. The quantity of the doping of the semiconductors is kept different so... View Article
Zener diode is a special type of diode that is designed to work in reverse condition. Under forward bias condition, the diode acts as a normal... View Article
One of the major differences between the diode and the transistor is that diode converts alternating current into direct current. Transistors... View Article
In an ideal case, the vapour pressure is hardly influenced by the atmospheric pressure because we ignore the intermolecular forces in ideal... View Article
Tension can either be positive or negative depending on where the coordinate axes are placed. Regardless of the upward direction being taken as... View Article
Yes, the radius of the pulley affects the tensions in the belt. For a given frictional torque at the axle, the difference in tensions between the... View Article
No, surface tension doesn’t depend on the surface area. Surface tension is a property displayed by the liquid surface by acting as if it were a... View Article
In reverse bias condition, the charge carriers are pulled away from the p-n junction; as a result, the width of the p-n junction gets wider. The... View Article
The reverse saturation current is the part of the reverse current in a semiconductor diode which is caused by the diffusion of minority carriers... View Article
Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from... View Article
The following conditions are necessary for a harmonic motion to be accounted for as a simple harmonic motion: The restoring force must be... View Article
