Where is the Focal point of a convex mirror?
The focal point of a convex mirror is located behind the mirror. It is the point where parallel light rays appear to converge after reflecting off the mirror's surface.
How would you find the focal point of a convex mirror?
To find the focal point of a convex mirror, you can use the formula: f = R/2, where R is the radius of curvature of the mirror. The focal point of a convex mirror is located behind the mirror, at a distance equal to half the radius of curvature.
Why is the focal length negative for a convex mirror?
The focal length is negative for a convex mirror because the light rays do not actually converge at a single point in front of the mirror. Instead, they appear to diverge from a virtual focal point behind the mirror.
What creates an image that is reflected through a focal point?
An image that is reflected through a focal point is created by parallel light rays that hit the concave mirror and reflect towards the focal point due to the mirror's curvature. This creates a real, inverted image at the focal point.
Why does a convex mirror have no focal point?
A convex mirror diverges light rather than converging it, so it does not have a real focal point like a concave mirror. The reflected light appears to be coming from a virtual focal point located behind the mirror. This property makes convex mirrors useful for creating a wider field of view in applications such as side mirrors on vehicles.

The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex mirror.

This property makes convex mirrors useful for creating a wider field of view in applications such as side mirrors on vehicles.
Why can't a convex mirror create a real image?
Because the focal point of the convex mirror will always be at a 'virtual' place. Convex mirrors focus the image at a definite point.
Which type of mirror causes light to spread out?
A concave mirror causes light to converge to a focal point, while a convex mirror causes light to diverge and spread out.
Does a concave lens affect light more like a concave mirror or a convex mirror?
A concave lens behaves more like a concave mirror because it diverges light rays away from a focal point, whereas a convex mirror converges light rays towards a focal point.
How do you derive relation between focal length and radius of curvature of convex mirror?
For a convex mirror, the focal length (f) is half the radius of curvature (R) of the mirror. This relationship arises from the mirror formula for convex mirrors: 1/f = 1/R + 1/v, where v is the image distance. When the object is at infinity, the image is formed at the focal point, and the image distance is equal to the focal length. Hence, 1/f = -1/R when solving for the focal length in terms of the radius of curvature for a convex mirror.
The image formed by a convex mirror?
The image formed by the convex mirror is virtual, erect and diminished.
Can a concave mirror act as a convex mirror?
No, a concave mirror and a convex mirror have different curvatures and focal points. A concave mirror reflects light inward, converging it to a focal point, while a convex mirror reflects light outward, diverging it. They cannot interchange their functions.
