Huygens' construction; Huygens' principle (C. Huygens):
The mechanical propagation of any wave (exclusively, of light) is equal to supposing that each point on the wavefront behaves as point source of wave emission.
consider an experiment where you drop an object. brieffly decribe your proposed experiment. what is the indepentent variable and dependent.
Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity
Difference among sound and light waves: (i) For propagation of sound rays material phase is required but no material medium is needed for light waves. (ii)Sound rays are long
What is the exact distinction between Diffraction and Interference?
In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use
A moving elevator and a ball or an object being dropped inside it with some given speed/acceleration. Ans) You must know the concept of inertial and noninertial frames.non inertia
1. Solve the TISE in each region to find the stationary wave function, and show that it can be written as ?(x) = Ae ikx +(k-1)/(k+1)Ae ikx x =2k/(k+1)Ae ilx x>0 where
Q. Why the centre of Newton's rings pattern appears dark? The thickness of the air film becomes zero at the point of contact of lens L with glass plate P. Therefore there is no
