Longitudinal Waves and Guitar Strings
According to the diagram this pressure wave consists of rarefactions and compressions. The compressions are regions of high pressure, whereas the air molecules are compressed within a small region of space. The rarefactions are regions of low pressure, while the air molecules are spread apart. This alternating pattern of compressions and rarefactions is called as a sound wave.
Q. A twelve-slit strobe disc is rotated at the max stopping frequency for a vibrating object. The strobe is rotated at 4.0 Hz. (a) Evaluate the period of the vibrating object?
WORK AND ENERGY 1. Work can be defined as: the force applied in direction of displacement ×. This means that if the force F acts at an angle θ with respect to the direct
A weakly guiding optical fibre propagates just two bound modes with scalar transverse electric fields ψ 1 (x,y) and ψ 2 (x,y), and propagation constants β1 and β2, respectively. At
When wave emitted by a self luminous object is dispersed by a prism to get the spectrum, the spectrum is known as emission spectrum.
RESISTANCE: An electric current is a flow of free electrons through a conductor. The size of current flowing through a conductor for a given applied voltage depends on: • T
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
What are the advantages of fibre optic communication? Advantages of fibre optic communication are as follows: a. Enormous band width Coaxial cable transmission of 500 M
Q. Two slits 0.3 mm separately are illuminated by light of wavelength 4500 0A. The screen is placed at a distance 1m from the slits. Find the separation among the second bright fri
How are glass fiber ended? Glass fibers are, usually potted or encapsulated at the single end with the help of an epoxy compound or adhesive. It results on a very hard element
The differential equation of motion of freely oscillating body is given by 2 d 2 x/dt 2 + 8π 2 x = 0. Evaluate the natural frequency of the body?
