Radio waves and microwaves:
What are microwaves and radio waves?
Ans: Microwaves:
1. The wavelength ranges from 10μm to10m
2. Commonly produced by Electromagnetic oscillators of high frequency
3. Used in telemetry microwave ovens and satellite communication
Radio waves:
1. The wavelength ranges from 1m to about 100km
2. Produced when electrons are accelerated in a suitable electronic circuit.
3. Used in carrying messages to long distances and in radio astronomy.
Energy gap: 2.4ev. The colour of pure cadmium sulphide is pale yellow. It melts only under at high temperature. It can be prepared in the resistivity range from 10 to

why the reflective index of cladding is lower then in core of a fiber optic?
Q. A capacitor of capacitance 2 μF is in an ac circuit of 1000 Hz. Compute the reactance of it. Solution: Capacitive reactance XC = 1 / ω C = 1 / 2π ν C =
Q. Why can a DC ammeter not read AC? a) Dc ammeter can't measure ac because ac is changing continuously and periodically as well as a dc ammeter can just measure a constant cur
