Doppler Effect
Describing the classical Doppler Effect for sound waves. The Doppler Effect is a means through that wave properties (specifically frequencies) are influenced through the movement of a source or listener. If you've ever been waiting at a railroad crossing and listened to the train whistle, you've in all probability noticed that the pitch of the whistle changes as it moves associatively to your position. Same, the pitch of a siren change as it approaches and then passes you on the road.
Determine the angle of incidence for a ray of light to have minimum deviation of 39040' in equilateral prism.
What is Fission and Fusion? Fission: The breaking down of a Nucleus (not atom) into minute nuclei. It is usually induced by a neutron. For instance, a Helium nucleus (known a
Depending upon the penetration power, there are two parts of X-rays Hard X-rays More penetration power More frequency of the order of ≈ 1019 Hz Lesser wavelength range
Give the basic construction of pentode Ans: Construction of Pentode: Constructional details of a typical pentode are demonstrated in fig. (a) and fig. (b) Pentode comp
Two moles of an ideal gas expands reversibly and isothermally to ten times its volume at 25°C. Evaluate the change in entropy during the process. ( R = 8.314 JK -1 mol -1 )
The power distribute to a 15 watt light bulb in normal operation is 15 watts. In normal operation how greatly energy is delivered to such a bulb in an hour? Feedback:
According to their frequencies, waves are separated into three categories: (1) Audible or sound waves : Range 20 Hz to 20 KHz. These are formed by vibrating bodies like as voc
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
What do you mean by nuclear fission? Illustrate liquid drop model of nuclear fission? Difference between nuclear fission and nuclear fusion. State the properties of α, β, γ ra
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
