define principal focus of a Convex lens and Concave lens
define the principal focus of a convex mirror
What is tyndall effect?Explain an example
A concave mirror produces three times magnified real image of an object placed 10 cm in front of it.Where is the image located
DEFINE RARER & DENSER MEDIUM.
why a convex mirror is used as rear view mirror
A student focussed the image of a candle flame
When an object is placed at a distance of 50 cm from a concave mirror , the magnification produced is - 1/2 . where should the object be placed to get a magnification of -1/5
The magnification produced by a plane mirror is +1. What does this mean?
a convex lens forms a real and inverted image of a needle at a distance of 50 cm from it. Where is the needle placed in front of the lens if the image size is equal to the object size. Also find the power of the lens
The refractive indices of water and glass with respect to air are 4/3 and 3/2 respectively. If the speed of light in glass is 2x 108ms-1, find the speed of light in
1. Air
2. Water
what r the properties of convex and concave mirror???
Define power of lens.In what SI unit is power of lenses rated?A convex lens has a focal length of 50cm.calculate its power.
The magnification produced by a mirror is 1/3 then the type of mirror is --------------. Explain why?
find the position of an object when placed in front of a concave mirror of focal length 20 cm produces a virtual image,which is twice size of object.
