Electrons are emitted from a photosensitive surface when it is illuminated by green light but electron emission does not take place by yellow light. Will the electrons be emitted when the surface is illuminated by (i) red light, and (ii) blue light.
If a force applied on a body causes a alteration in the normal positions of the molecules of the body, resulting in a alteration in the configuration of the object either in length
describe the construction and working of a Nicol prism.discuss how you obtain a plane polarised beam with it?
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) momentum but not energy b) neither moment
These resistors change their resistance with variations of incident light energy. MANUFACTURING: Cadmium sulphide is obtained in a highly pure state. By adding special m
A 2.0-kg projectile is fired with initial velocity components v0x= 30m/s and v0y= 40m/s from a point on the earth's surface. Neglect any effects due to air resistance. What is the
The magnetic vector potential in a specific region is a constant vector having magnitude 4πX10 5 units and points along the positive x-axis. What is the magnitude of the magnetic
Explain the Conservation of Momentum In a collision, energy is not all time conserved, if not the collision is totally elastic (all stored energy is turned into kinetic energy
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
Consider the water heat distribution system shown below where: The fractions refer to the fraction of the stream ?owing, e.g. 20% of the stream leaving the 100,000 Btu/ hr heate
For SHM to occur, three conditions must be satisfied. 1.There must be a position of stable equilibrium. At the equation in equilibrium potential energy is minimized. That is,
