write 3 difference between concave and convex lens?
write 3 differences between real and virtual images?
What is meant by lateral displacement?
What is the meaning of virtual and erect image???
derivation of mirror formula as well as lens formula ?
define power of lens and gives its S.I.unit
State the Principle of reversibility of light
explain..why a pencil partly immersed in water appears to be bent at the water surface
what is tyndall effect?
define absolute refractive index of a medium.?
WHAT IS VIRTUAL AND ERECT IMAGE
One half of a convex lens is covered with a black paper.will such a lens produce an image of the complete object?support your answer with a ray diagram.
plz ans. fast as i hv a revision test on monday
write 3 differences between reflection and refraction
refractive index of glass with respect to air is 3/2..refractive index of water with respect to air is 4/3..what is the refractive index of glass with respect to water?? is it 3/2 divided by4/3 or 4/3 divided by 3/2??
an object is placed at a distance of 10 cm from a convex mirror of focal length 15cm. find the position and nature of the image.
