Light Reflectio...

The time required to pass the light through a glass slab of $$2\ mm$$ thick is $$(\mu_{glass}=1.5)$$

Which of the following ray diagram show physically possible refraction

A medium shows the relation between the angle of incidence $$i$$ and the angle of refraction $$r$$. If speed of light in the medium is $$nc$$ then value of $$n$$ is 

A concave mirror of focal length $$15\ cm$$ forms an image having twice the linear dimensions of the object. The position of the object when the image is virtual will be 

The ratio of thickness of plates of two transparent medium $$A$$ and $$B$$ is $$6:4$$. If the takes equal time in passing through them, then refractive index of $$B$$ with respect to $$A$$ will be

An object $$1\ cm$$ tall is placed $$4\ cm$$ infront of a mirror. In order to produce an upright image of $$3\ cm$$ height one needs a

What is the time taken $$(in\ s)$$ to cross a glass of thickness $$4\ mm$$ and $$\mu=3$$ by light?

A convex mirror has a focal length $$f.$$ A real object is placed at a distance $$f$$ in front of it from the pole produces an image at 

Match List $$I$$ with List $$II$$ and select the correct answer using the codes given below the lists:

The absolute refractive indices of water glass and diamond are 1.77, 1.50, and 2.72 respectively, which medium is most optically denser?
