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]].
A) Explain the flow of direct current? ( describe direct current) b) Explain the effect of resistance in circuits? (Describe effect of resistance)
Q. Illustrate what are the weights in pounds of liquid gallons? Answer:- First you should know the specific gravity of the liquid then you can compute the weight by multip
Fibre optics: Light travels in straight lines, even though lenses and mirrors can deflect it, light still travels in a straight line between optical devices. This is fine for
Fermat's principle; principle of least time (P. de Fermat): The principle put by P. de Fermat, which states the path taken through a ray of light among any two points into a s
Eddy currents can be briefly explained as currents produced due to induced emf in the form of eddies or ripples. Hysteresis laws mainly consists of 2 topics retentivity and coerci
Would a nail rust in oil and water or water and oxygen?
Q. An emf of 5 V is persuading when the current in the coil changes at the rate of 100 As-1. Find the coefficient of self induction. Solution: Induced emf e = - L dI/dt
Vertical Circular Motion A mass is in circular motion within the vertical plane. We show the weight and force exerted through the tension within the string.
Are the optics efficient as a means to transport the light? No, optics is not efficient as a means to transport the light. If we take any other means of light distribution or
These resistors change their resistance with variations of incident light energy. MANUFACTURING: Cadmium sulphide is obtained in a highly pure state. By adding special m
