Assertion: Magnification of spherical lens has no unit
Reason Magnification is the ratio of two simile quantities
Q2. Assertion: The angle of incidence for a ray of light having zero angle of reflection is 2 To Reason Reflecting surface follows Snell's law
Q3. Assertion:
A concave mirror of radius R is placed in water. is focal length in air and water differ.
Reason equal to R/2.
The focal length of the concave mirror of radius R is
04. Assertion: Power of concave lens is negative and that of convex lens is positive
Reason : For diverging lens focal length is taken as negative and for converging lens focal length is taken as positive.
Q5. Assertion : Lateral displacement is the perpendicular distance between incident ray and the emergent ray.
Reason :The wider the glass slab, the larger the lateral displacement
