True/False : The light is first and maximum refracted as it passes through eye lens.

True/false: Incident ray and refracted rays are parallel to the normal

State whether the following statements are True or False : The incident ray and refracted ray of light are on the opposite sides of the normal at the point of incidence

True/False: A lens is an opaque object.

Answer the following questions : In the case of a convex lens , show the path of the refracted ray when the incident ray of light is parallel to the principal axis of the lens passes through the focus of the lens passes through the optical centre of the lens.

Answer the following questions : In general, when a ray of light passes through a lens , there occurs a change in its direction of propagation . Why?

True/false: Light has different velocities in different media.

A ray of monochromatic light is incident on one refracting face of a prism of refracting angle 75^(@) . It passes through the prism and is incident on the other face at the critical angle If the refracive index of the material of prism is sqrt(2) , the angle of incidence on the first face o the prism is

If the object is placed at A and the image is formed at B when the rays are refracted through a convex lens. The position. Of A and B are changeable. Such pair of is called.

True/false: The speed of violet light is less than that of red light in prism.

State whether the following statements are True or False : The wavelength of orange light is greater than that of blue light.
