1. What do you understand by diffraction of waves? Explain why the diffraction of sound is more easily observable than the diffraction of light?
2. The wavelength of two spectral lines are 589 μm and 588 μm. what is the minimum number of lines a grating must have in order to resolve these lines in the first order spectrum?
Uses of Radio Isotopes: Industries: 1. Radio active isotopes are used to detect leakage in pipes. 2. It estimates weak and tear machine tools. 3. It is used to check t
1. We want to measure a sinusoidal signal (frequency 100 Hz) expected to be of strength 1 mV RMS in the presence of noise of peak amplitude 3 mV. (a) If our A/D converter has
Can radiations like gamma rays and x-rays be made prevented to enter a place by a magnetic field? Ans) Rutherford noted that gamma rays were not deflected (or at least, not easi
two travelling sinusoidal waves are described by the wave function, y=55
PROJECTILE: "When a body is thrown upward making a particular angle 'Q' with the horizontal and moves freely under the action of gravity, it is known as a projectile". EXAMP
A particle with mass m = 2:5 is moving along a straight trajectory. The distance covered by a particle is described by the function S(t) = t 3 + 2t 2 , where t > 0 is the time
A simple electric circuit, where current is represented by the letter i. The relationship among the voltage (V), resistance (R), and current (I) is V=IR; this is called as Ohm''s L
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.
Explain why a narrow slit is used in case of Bi-prism experiment where as an extended source is used in Newton's rings experiment?
A centrifugal fan is used to pump air. The fan rotor is 1 ft in diameter, and the blade spacing is 2 in. The air enters with no angular momentum and exits radially with respect to
