Detection (Receiver): The antenna receiver these modulated waves from different transmitting stations.
Channel selector selects the desired signals. The selected signals are amplified and converted into light pulse in such a way as to reconstruct the image of the original object on the screen. At the same time, sound waves are extracted. The T.V. Set known as kinenoscope converts the electrical signals into light signals.
Imagine a small observer is positioned in front of the cork in your picture above. As the cork approaches, the observer measures the wavelength of the waves passing by. How does th
how dielectric mat is used for high voltage safety ? how it works?
Draw a graph showing the variation of potential energy of a p of nucleons as a function of their separation. Show the regions in which nuclear force is (i) attractive, and (ii) rep
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0). Thus from first law of thermodynam
(a) Show that the total power in a 3-phase, 3-wire system using the two-wattmeter process of measurement is given by the sum of the wattmeter readings. Illustrate a connection diag
The characteristics of substance by virtue of which it opposes the flow of current by it, is called as the resistance.
FRAME OF REFERENCE: "A set of reference axis needed to locate the position of an object in space is known as a frame of reference"
(i) A matter pulse is not electromagnetic in behavior. (ii) Practical observation of matter waves is possible only when the de-Broglie wavelength is of the order of the size of
The engine on a motorcycle hums at 85 Hz. If the motorcycle travels toward a resting observer at a velocity of 29.6 m/s, what frequency does the observer hear? Use 343 m/s
