Can you explain Doppler effect? Find a mathematical expression for the apparent frequency heard when the source is in motion and the listener is at rest and also give limitation of Doppler effect?
In the Compton effect, a photon of wavelength l collides with a stationary electron. The wavelength of the emitted photon is: a) longer than l b) shorter than l c)
operation symmetry
YES GRAVITY CAN BAND LIGHT e.g. GRAVITY OF BACK HOLE IS VERY STRONG
Q. When the negative feedback is practical to an amplifier of gain 50 the gain falls to 25. Compute the feedback ratio? Af = A / 1 + Aβ 25 = 50 / 1 + 50 β 1 = 2 / 1 + 50
A weakly guiding optical fibre propagates just two bound modes with scalar transverse electric fields ψ 1 (x,y) and ψ 2 (x,y), and propagation constants β1 and β2, respectively. At
