Refractive Index:
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing single medium to another medium. This constant is called as refractive index of second medium with respect to the one
Explain about the intermodal dispersion in optical fibers. Intermodal Dispersion Δτ im ) This dispersion arises even when light that is launched into the fiber is s

What do you mean by beats? Illustrate the importance of beats. What are applications of ‘Doppler Effect'?
Total height of the gymnast just before falling back down is=(2+.3)=2.3m Energy gained at that point = m*g*h(m=mass, g=gravitational force, h=height) =55*9.8*2.3=1239.7 J
Laws of Refraction: There are two laws of refraction. The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plan
Lyman series: The series which define the emission spectrum of hydrogen while electrons are jumping to the ground state. All lines are in the ultraviolet.
A 3300V/440V, single-phase transformer takes a no-load current of 0.8A and the iron loss is 500W. Draw the no-load phasor diagram and Determine the values of the magnetizing
How long does it take for reach that speed
When a spherical body goes by a viscous fluid, it feels a viscous force. The value of the viscous force increases with the enhance in speed of the object falling under the function
