Define the use of quartz crystal method to detect ultrasonic waves.
Quartz crystal method:
This method is based onto the principle of Piezo-electric effect. While one pair of the opposite faces of a quartz crystal is representation to the ultrasonic waves, other pairs of opposite faces expanded opposite charges. Such charges are amplified and detected by using an electronic circuit.
Coulomb's law (C. de Coulomb) The primary law for electrostatics is analogues to Newton's law of universal gravitation. This states that the force among two point charges is p
Air dielectric capacitors are used mainly as laboratory standards of capacitance for measurement purposes. The insulating material used in these capacitances is fused silica and th
A physics student performs a double-slit diffraction experiment on an optical bench, as shown in the figure below. The light from a helium-neon laser has a wavelength of 632.8
Linear circuit :- It can be described as one, whose parameters are constant i.e. they do not change with voltage or current.
Q. Compute the resistance of the filament of a 100W, 220 V electric bulbs. Power P = V 2 /R Resistance R = V 2 /P = (220 X 220)/ 100 = 484 ohm.
Q. What is dual character of light? Light behaves as particles of energy in the higher energy region as well as as waves in the lower energy region.
