What will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?

Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the mirror.

The focal length of a concave mirror will decrease when the incident violet light is replaced by red light, as red light has a longer wavelength. Conversely, the focal length of a convex mirror will increase because red light is less divergent compared to violet light.

What happen when put convex and concave With some?
When a convex lens and a concave lens are placed together, they can form a compound lens system known as a lens system. Depending on the relative orientations and distances between the two lenses, the resulting system can either magnify, diminish, or correct the incoming light rays. This configuration is commonly used in optical instruments such as microscopes and telescopes to manipulate the path of light rays.
What would happen if concave mirror is missing in projector?
If the concave mirror is missing in a projector, the light rays from the light source won't be properly focused onto the screen. This would result in a blurry and distorted image being projected, as the concave mirror is responsible for directing and converging the light rays to create a clear image.
Describe what happen to parallel light rays hitting in a concave mirror?
Parallel light rays hitting a concave mirror will converge to a single focal point after reflection, due to the mirror's inward or converging shape. The focal point is located on the principal axis of the mirror, halfway between the mirror's center and the vertex. This property of concave mirrors is used in applications like focusing light in telescopes and for creating images in reflective devices.
What will happen if cover half of the concave mirror?
If you cover half of a concave mirror, the reflected image will be dimmer, smaller, and less clear compared to when the mirror is fully uncovered. This is because the covered portion of the mirror is unable to reflect light, leading to a partial or distorted reflection.
What will happen to the parallel raysof light after falling on a convex lens and passed through the lens?
The parallel rays of light will converge at a focal point after passing through a convex lens. The convex lens will refract the light rays and bring them together at a single point called the focal point.
