What is accommodation and it's effects?

Write a program to explain the how the intensity varies as a function of phase difference / path difference in interference of two sinusoidal waves.

A ray of light incident normally on one of the faces of a prism of apex angle 30 degrees and refractive index (2)^0.5 , the angle of deviation is .

Consider a plane wave incident on a convex lens of diameter 5cm and of focal length 10cm. If the wavelength of the incident light is 6000°A, calculate the radius of the first dark ring on the focal plane of the lens. Repeat the calculation for a lens of same focal length but diameter 15cm. Interpret the result physically.

A diffraction phenomenon is observed using a double slit illuminated with light of wavelength 5000 °A. The slit with is 0.02mm and spacing between the two slit is 0.1mm. The distance of the screen from the slits is 100cm. Calculate
(1) distance between central maximum and first minimum of the fringes envelope.
(2) distance between any two consecutive double slit dark fringes
(3)amplitude and intensity.

A convex lens of power +5D was used to produce a virtual magnified image 5 times the size of the object. Determine the object and image position

An object is placed 6cm from a convex mirror of focal length 3cm. Find the image distance, its magnification and properties

Shine a flashlight through a clear drinking glass. Try to make a visible spectrum in the image made from the glass. If you can, note the conditions necessary for the spectrum to occur – specifically the distances or angles necessary.

When shining the light through the drinking glass, why was a spectrum not visible all of the
time? What factors would change whether a spectrum is visible, and why?

Color A and color B are sent through a prism. Color A is bent more than color B. which travels more rapidly in the prism?

A light beam undergoes total internal reflection at the interface between medium A, in which it propagates, and medium B, on the other side of the interface. Which medium has the greater index of refraction? Explain.
