What happens when you direct light waves at an angle into a mirror?
According to wave-based theories, the light waves spread out from the source in all directions, and upon striking a mirror, are reflected at an angle determined by the angle at which the light arrives. The reflection process inverts each wave back-to-front, which is why a reverse image is observed.
How do you find a normal in spherical mirror?
you can draw a perpendicular to the point on the mirror ,it will give you the normal. Take any point on the circumference of the mirror . Draw 90• line or pependicular to it . This is its normal.
What is focus of a concave mirror?
Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.
What type of focus a concave mirror has?
Concave mirrors A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.
What are the applications of concave mirror?
Uses Of Concave Mirror
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
How do you use a convex mirror?
Convex mirrors are also used in various other places like as a street light reflectors as it can spread light over bigger areas. They are also used to make telescope and ceiling dome mirrors….Convex mirrors used for security purposes.

What is the focal length of a convex mirror whose radius of curvature is 64 cm?
So focal length of the convex mirror will be 16 cm.
What is the focal length of concave mirror whose radius of curvature is 80 cm?
Answer. seee…..the focal length of concave/convex mirror = half of its radius of curvature…..
What is the focal length of a concave mirror whose radius of curvature?
If the radius of curvature is 150 cm. then the focal length is 75 cm. The light will converge at the focal point, which is a distance of 75 cm from the mirror surface….The Anatomy of a Curved Mirror.
