Planck radiation law
A law that defined blackbody radiation better than its predecessor, therefore resolving the ultraviolet catastrophe. It is depend on the supposition that electromagnetic radiation is quantized.
At thermodynamic temperature T, for a blackbody, the radiancy R onto a range of frequencies among nu & nu + dnu is provided by
R = 2 pi h nu3/[c3 [exp (h nu/k T) - 1]].
Charge is the characteristic associated with matter due to which it produces and experiences electrical and magnetic effects.
Friction has several disadvantages but life is impossible without friction because friction has many benefits also.
Anode rays were discovered by: (1)Goldstein (b)J. Stoney (3)Rutherford (4)J.J. Thomson Ans: (1)Goldstein
Q. In a galvanometer, increasing the current sensitivity does not necessarily increase voltage sensitivity. Explain An interesting point to note is that raising the current sen

Explain the Electromagnetic Induction The force exerted on an electric charge moving in a magnetic field leads to the idea of magnets being able to produce electricity as well
As a longitudinal wave moves through a medium, the particles of the medium: a) vibrate in a path parallel to the path of the wave b) vibrate in a path perpendicular to the p
VELOCITY: The time rate of change of displacement of a body is known as velocity. It is represented by V ?.
MANUFACTURING: T hese resistors do not require substrate. Resistive material is a mixture of finally ground graphite, filter and resin blander. Filter is usually silica. The mix is
