Refractive Astronomical Telescope:
It is an optical instrument which is used to see heavenly bodies such as stars, moon and planets is known as telescope.
Astronomical telescope having of a long metallic tube of variable length, two converging lens are mounted at its two ends.
Convex lens of large focal length and big aperture is known as objective.
Convex lens of shorter focal length and large aperture is known as eye piece.
Working:
The objective forms a real and inverted image of the object. This image is very small as compared to the object. The eye piece is used as magnifying glass. The final image is inverted and brighter than the object.
Frequency The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz. V=1/T
operation symmetry
Will light go any length along the fiber? Each conductor has losses, and in the case of fiber optics, all these are sizeable. Light losses into the industry average 2 to 5 perc
It is a measure of how easily a dielectric material polarizes in response to an electric field.
With the help of a neat and labelled diagram, describe the underlying principle and working of a moving coil galvanometer. What is the function of? (i) Uniform radial field
Oxygen effect: The oxygen effect may play a role in the recurrence of cancer .The cell near the center of a large tumor have a poor blood supply and thus a poor oxygen supply
What are the types of fibre optics?
What are benefits of fiber-optic sensors for harsh environments? Benefits of fiber-optic sensors for harsh environments are illustrates below: a. Small, contact measurements
show that in a glass prism that the refractive index n = sin1/2(A+Dmin)/sin1/2A where a = refracting angle. hence if the angle of incidence i on oan air boundary is 60degrees. calc
An equiconvex lens has the radius of one curved surface is 0.12 m and focal length of 0.10 m. Determine the refractive index of the material of the convex lens.
