Spectrum and electromagnetic radiations:
What is a spectrum?
Ans: A spectrum is a group of wave lengths or frequencies.
What are the electromagnetic radiations?
Ans: Electromagnetic radiations are characterized by oscillating electric and magnetic fields perpendicular to each other and also perpendicular to the direction of propagation. All these radiations travel with the same speed,that is 3 x 108m/s2.
A rigid object is a body with a exact and unchanged size and shape i.e. a body is said to be rigid if the distance among any two particles of the body remains invariant.

What is a capacitor ? A capacitor is basically a two conductors conencted with an insulator.... It stores great amount of charge!
1. A 12-bit analog-to-digital converter (ADC) works over the range of -5 volts to + 5 volts. (a) What is the voltage resolution of this converter? (b) Assuming -5 V is rep
(i) A disk shaped flywheel of uniform density _, outer radius R and thickness w. rotates with angular velocity _, obtain an expression for the moment of inertia 2 vol I =_ρ r dV
Why because it is not a source as Li-ion battery. If we want to measure the voltage(build in voltage) with in the diode we have to use the external source. We can''t directly measu

Wave motion is the motion in which the particle/matter remains at the point where it is. But the disturbance/energy gets transfer from one point to the other. The particle just o
What is the difference between the Atomic Theory and the Kinetic Theory? Atomic theory is all about structure of an atom, i.e., its composition. Like an atom in general is made
