Define the term multi-mode fibre shortly.
Multi-mode fibre:
This type of fibre permits more than one mode to travel by this. As this has to permit more number of modes to travel which, the fibre has to have a larger core. A classical multimode fibre has a core diameter in order of from 150 to 200µ m. That a large core permits more number of modes to travel but also makes this easier to launch the light in fibre and to join two fibres together. Conversely, larger the number of modes, larger will be the dispersion of light into the fibre.
Basic principles of spectrophotometry: An absorbance spectrophotometer is an instrument that measures the fraction of the incident light transmitted through a solution
Fig- detremines a square loop Made from a uniform wire. Determine the magnetic field at the centre of the square if a battery is connected among the points A and C.
What do you mean by Doppler effect? Derive a mathematical expression for the apparent frequency of a note, when source of sound and observer are approaching each other.
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
