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]].
Explain the meaning of Diffraction The spreading of a wave around a corner or through a slit of width b, which is about an order of magnitude of the size of the wavelength, is
Describe the working of the ultrasonic magnetostriction method. Working: The rod is permanently magnetized within the beginning through passing direct current. Then batter
Q. What do the negative sign tell you about the image? A single lens is utilized to form an image of an actual physical object. You compute the image position i and find that
A charge is said to be in equilibrium, if total force performing on it is zero. A operation of charges is said to be in equilibrium if every charge is independently is equilibrium.
HYSTERESIS LOOP: A ferromagnetic material retains some magnetism after the magnetising force is removed. The BH curve (O to Q) will therefore only be followed once, on initial
Question 1. Discuss the general guidelines to be followed for whole body CCT 2. Describe pitch and image quality in MSCT 3. List the advantages of SCT in pediatrics. Expl
An electrical dipole is just a separation between a negative and positive charge of the same magnitude. Consider that a dielectric material is exposed to an electrical field. The e
The points of maximum amplitude are called as antinodes. At ends density and air pressure both are very low.
how we make assigment
The speed at which a wave propagates down a string is 300 meters per second. If the frequency of this wave is 150 Hertz, what is the wavelength of this wave? Ans: The wavel
