1. A very narrow laser beam is shone into a sphere of solid glass that has uniform refractive index n>1 and radius ρ . The beam makes an angle α in air with the normal to the surface of the sphere.
Sketch the path of the beam in the circular cross-section of the sphere defined by the normal and the beam direction and show all reflected and transmitted rays. Using Snell's Law at each reflection, explain why the beam cannot become a whispering gallery ray propagating around the inner surface of the sphere.
2. An asymmetric, multimode, step-profile slab waveguide has a core index of 1.5. The cladding index above the core has value 1.49 and the cladding index below the core has value 1.48. Rays propagate in the core in the x-z plane and make an angle θz relative to the z-axis along the centre of the waveguide.
(a) Determine the range of (positive) values of θz in degrees for which only bound rays will propagate along the waveguide.
(b) How many different types of rays can propagate along the waveguide?
Sketch a typical path for each type of ray.
(c) Determine the values of θz in degrees that delineate between the 3 types of ray paths.
Phase (Φ) : The amount which express at any instant, the displacement of the particle and it's direction of motion is known as the phase of the particle. If two elements of the

It is a highly doped p-n junction which is not smashed by high reverse current. The breakdown voltage is made very sharp. In the forward bias, the zener diode do as ordinary diode.
Chandrasekhar limit (S. Chandrasekhar; 1930) This is a limit that mandates that no white dwarf (a collapsed, degenerate star) may be more massive than approximates 1.4 masses
Quality: It is the characteristics of a sound by which we can distinguish among two sounds of the similar pitch and the loudness is known as quality of sound.
