A plane monochromatic wave travelling in a homogeneous medium goes into a denser medium. What are the changes in (i) Frequency (ii) amplitude (iii) speed of propagation & (iv) Phase of transmitted and reflected wave in comparison with the corresponding properties of the incident wave.
two insulated charged copper spheres A and B of identical size have charge q and -3q respectably .when they are brought in contact with each other and then separated,what are the n
NEWTON'S FIRST LAW AND INERTIA: All the material bodies possess the property of opposing any alter in the state of rest or uniform motion when some external force is applies up
Polygon of force This topic just builds on the previous Triangle of Forces. Consider three forces A, B and C. A and B can be added by drawing a triangle to give a re

Energy is transmitted in a plane in two mutually perpendicular directions. Example : Wave propagating on the surface of water.
Question: In that piece of a circuit outside of any batteries or power supplies what is it that actually pushes charged particles through the circuit? Answer: By defini
Two travelling sinusoidal waves are described by the wave functions Y1 = 55.00 sin[π(4.00x - 1200t)] Y2 =55.00 sin[π(4.00x - 1200t - 0.250)] where x, Y1 , and Y2 are in meter
