What is the focus in a concave mirror ray diagram?
The focus is the point where collimated (parallel) light converges after reflecting off the mirror; its distance from the mirror's apex is called the focal length.
How does a ray parallel to the central axis reflect in a concave mirror?
A ray parallel to the central axis reflects through the focus of the concave mirror.
What happens to a ray that passes through the focus before hitting a concave mirror?
A ray passing through the focus reflects off the mirror parallel to the central axis.
How does a ray directed at the apex of a mirror reflect?
It reflects at the same incident angle, following the law of reflection.
How is the image formed by a concave mirror when the object is beyond the focal point?
The image is real and inverted, formed where the reflected rays converge below the central axis.
What happens when an object is placed at the focal point of a concave mirror?
No image is formed because the reflected rays are parallel and never converge.
What is the apparent focus in a convex mirror?
The apparent focus is a point where reflected rays seem to converge, but in reality, the rays diverge and never actually meet.
How does a ray parallel to the central axis reflect in a convex mirror?
It reflects away from the focus, diverging from the mirror.
What happens to a ray directed towards the focus in a convex mirror?
It reflects off the mirror parallel to the central axis.
What type of image does a convex mirror always produce?
A convex mirror always produces a virtual, upright image.
What is the focal length of a plane mirror?
The focal length of a plane mirror is considered to be infinity, as it neither converges nor diverges light.
How does a ray parallel to the central axis reflect in a plane mirror?
It reflects off the mirror parallel to the central axis.
Where does the image appear in a plane mirror relative to the object?
The image appears the same distance behind the mirror as the object is in front of it.
What type of image does a plane mirror produce?
A plane mirror always produces a virtual, upright image of the same height as the object.
Which type of mirror can produce real images?
Only concave mirrors can produce real images, as they converge light; convex and plane mirrors cannot.
