Properties of light:
The wavefronts can be of different shapes depending on the size and shape of light source and the distance from it. Huygens' principle states that every point on a wavefront behaves as the source of small secondary wavelets which spread out in all directions with a velocity equal to the velocity of light. The new wavefront is then found by constructing a surface of envelope tangential to the secondary wavelets.
Applying Huygens' principle, the phenomenon of reflection and refraction could be explained. The velocity of water waves depend on the depth of the water. The principle of superposition of waves states that when two or more waves travel through the same portion of a medium simultaneously, the resultant displacement at any point is the vector sum of the displacements due to the individual waves.
What is curvilinear motion? Basically, it's any motion that's produced or bounded by curved -- as opposed to straight -- lines. In high school, curvilinear motion is usually
Newtons Laws Skydiving Assume the motion of the skydiver below. As the skydiver falls and he encounters the force of air resistance. An amount of air resistance is dependent up
Q. Illustrate how do you find your body volume using a tape measure? Answer:- Correctly measure a container into which your body will fit comfortably. Previously you recog
FORCE ON THE PARTICLE: For a mass m to have acceleration, a force given by F = ma is always required. In uniform circular motion, acceleration is of value v2/t and is directed tend
Illustrated below are 5 of the normal modes of ethylene (HCCH). At its equilibrium geometry this molecule has no dipole moment, but for some of the normal modes the distortion dur
Q State Kirchoff's first law in electricity? Kirchoff's first law (current law) the algebraic total of the currents meeting at any junction in a circuit is zero. This law
Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
