Critical angle in certain substance is 300. Calculate the polarization angle of the substance?
Q. State Brewster's law. Brewster's law the digression of the polarising angle is numerically equal to the refractive index of the medium. That is tan ip = μ
The total energy of a simple harmonic oscillator is 0.8 erg. What is its kinetic energy when it is midway between an extreme position and mean position?
1)The armature ABCD consists of a copper wire wound on cylindrical soft-iron core.The armature can be rotated horizontal axis perpendicular to magnetic field. 2)NS is permanent
UV radiations and X - rays are: UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1n
ROCKET PROPULSION: The motion of a rocket is an application of the law of conservation of momentum and Newton's 3rd law of motion. The gases ejected out from the combustion cha
A tunning fork produces 4 beats per second with another tunning fork of frequency 256 Hz. The first one is now loaded with a little wax and the beat frequency is found to enhance t
Attraction & repulsion of atom: It can be observed, that if two negatively charged bodies are brought together, there is a force of repulsion between them. Similarly if two p
The opposition offered to the circular motion of bodies like sphere, disc, ring, cylinder etc. on another surface is known as rolling friction.
why newtons 2nd law is called the real law of motion?
Explain the Kinetic Theory Kinetic theory looks at how each of these steps adds more internal kinetic energy (jiggle energy) to the material. A solid is a framework of atoms an
