Light waves are propagating in vacuum. Derive the wave equation for the

associated magnetic field vector. On the basis of this equation, calculate the speed

of light.

The distance between the image and the object in a plane mirror is 40cm if the distance of the object is reduced by 9.2cm, what is the distance of the object from the mirror?

A flower is placed 12.0 cm in front of a mirror. If an image of the flower is formed 3.0 cm in front of the

mirror, what kind of mirror is it and what is the focal length of the mirror?

if an object is placed at 40 cm and its image is formed at 2 times focal length, where the image is inverted? then name the types of lens and find where the image is formed.

A grating has 10,000 lines per cm. Calculate the maximum number of principal maximum that can be formed for light of wavelength 487 nm.

A glass wedge of angle 0.01 radius is illuminated by a monochromatic light of wavelength 6330 falling normally it. At what distance from the of the the 20th fringe is observed

A ray EF of monochromatic light is incident on the refracting AB of a regular glass prism(refractive index=1.5)at an angle of incidence i=55°.if it emerges through the adjacent face AC..calculate angle of emergence

why is it difficult to achieve laser action (stimulated emission) at higher frequency range like x-rays?

Show that the plane polarized light and circularly polarized light are the special cases of elliptically polarized light

an extended source of light whose linear dimension is 0.3nm is used in young's double slit experiment .calculate the maximum seperation between the slits for which interference pattern will be observable if the wavelength of light is 580nm and seperation between the source and the slits is 0.50m.
