Explain the formula of the Stefan law.
STEFAN'S LAW:
P = σ AT4
Here:
P = Power radiated into W (J/s)
σ = Stefan's Constant 5.67 x 10-8W m-2K-4
A = Surface area of body (m2)
T = Temperature of body (K)
Thus the power radiated is proportional to T4 for an identical body that describes why the region under the black body curves (the entirety energy) increases too much for a relatively small raise in temperature.
A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase. In comparison to air velocity of sound is main in water,

Con you describe harmonics? How are stationary waves formed in a closed pipe? Illustrate the various modes of vibrations in a closed pipe and establish the relation between their f
What are Newton s laws of motion? 1. A body at rest will stay at rest and one in motion will stay in motion, unless and unless acted upon by an external force. (Law of inertia)
Frequency:- The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
Melting point: 525 0 C. It has small band gap and very high mobility around 70,000Cm 2 /V-Sec. It has much easier to prepare in single crystal from the Gallium arsenide. It is
