Refraction law:
For a wavefront travelling by a boundary among two media, the first along a refractive index of n1, and the other with one of n, the angle of incidence theta is associated to the angle of refraction phi by
n1 sin theta = n2 sin phi.
Pitch: It is the characteristics of a sound by which we can distinguish among a grave and shrill sound is known as pitch. It depends on frequency of the vibrating body and expr
Friction is a microscopic constant and so macroscopic level area does not matter. But area would matter if the object we''re putting under study was microscopic, which isn''t in o
A small air bubble is placed 0.04 m inside a glass sphere of refractive index 1.5. When viewed normally from outside it is seen at a depth of 0.03 m. Determine the radius of curvat
What is the measure of the force of gravity on an object? Force is the vector product of mass and acceleration: F = ma. Weight is a special case of that formula, where you subs

Passing Lane A passing lane or overtaking lane is the lane on a multi-lane highway or motorway closest to the center of the road or the central reservation.
Is photon a particle or a wave? What is its rest mass? Can X-ray generate photoelectric effect? Determine the work function of a metal production photo electrons with X-rays of
Q. What is a frame of reference? A system of co-ordinate axes which describe the position of a particle in two or three dimensional space is called a frame of reference.
What do you mean by photo electric effect? Show the laws of photoelectric effect. Illustrate these laws using Einstein's equation of photo electric effect?
It is worth noting that positive charges have lines of forces moving out from them and negative charges have lines of forces entering them.for attraction of charges one charge must
