DERIVATION OF MIRROR FORMULA.
suggest me a working model project in physics
what is the meaning of scattering of light?
Derive an expression for the focal length of the combination of two thin lenses when they are SEPERATED by a small distance?
difference between extrinsic and intrinsic semiconductor
cbse XII physics investigatory project-
3.To find the refractive indices of (a)water (b) oil (transparent) using a plane mirror , a equiconvex lens and an adjustable object needle.
For the same value of angle of incidence the angle of refraction in three media A,Band C are 15 degree,25 degree and 35 degree respectively.in which medium the velocity of light be minimum?
how does focal length of a lens depends on the wavelength of light passed through?according to me the focal length should not change as focal length is a physical quantity of a lens so it should not change.
derive F=R/2 for convex mirror
Why the uv graph of concave mirror is parobilic and1/u and1/v graph is a linear graph???
derive lens maker formula by concave lens
A convex lens of focal length 20cm is placed coaxially with a convex mirror of radius of curvature 20cm. The two are kept 15 cm apart. A point object is placed 40cm in front of the convex lens.Find the position of the image formed by the combination .
Which mirror is a convergent mirror? What type of image is formed by it? Can thevirtual image be screened or photographed?
Diameter of a plano - convex lens is 6 cm and thickness at the centre is 3mm. If speed of light in material of
what is plane glass plate????
