What is the center of curvature of a plane mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
When an object is placed at c of a concave mirrorthe image will be formed at?
When an object is placed at the center of curvature (C) of a concave mirror, the image will be formed at the center of curvature (C) on the other side of the mirror. The image produced will be inverted and the same size as the object.
Formula of radius of curvature of double convex lens?
The formula for the radius of curvature (R) of a double convex lens is given by R = 2f, where f is the focal length of the lens. The radius of curvature is the distance from the center of the lens to the center of curvature of one of its curved surfaces.
Why is the ray passing through centre of curvature reflects along the same path?
When a ray of light passes through the center of curvature of a concave mirror, it reflects back along the same path because the angle of incidence is equal to the angle of reflection. This is a property of mirrors where the reflected ray follows the law of reflection, resulting in the ray retracing its original path.
What type of mirror could be used to A real image as big as real object?
Concave mirror is used to a real image as big as real object. If the object is placed at center of curvature , then real image is formed at the same center of curvature.
What is difference between curvature and radius of curvature?
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
Why do the light pases without bending from center of curvature?
well if you try to send light through a curve glass it will bend except in the middle its because the middle of the glass is the focal point of the glass .the ray doesn't bend though the curve is a normal glass a concave mirror or a convex glass it appers the same from the other side
If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
What are the four principal rays of curved mirror?
The four principal rays of a curved mirror are: the ray parallel to the principal axis that reflects through the focal point after reflection, the ray that passes through the focal point before reflection and becomes parallel to the principal axis after reflection, the ray that passes through the center of curvature and reflects back along the same path, and the ray that strikes the mirror at the center of curvature, reflecting back along the same path.
Do certain sunglasses actually block out harmful UV rays?
Pretty much all sunglasses block out harmful UV rays, thats what they are made for. Some block out more than others, but they all do the same job.
Can focal length and radius of curvature of a lens be same?
No, the focal length and radius of curvature of a lens cannot be the same. The radius of curvature is twice the focal length for a lens. This relationship is based on the geometry of the lens and the way light rays converge or diverge when passing through it.
Can regular glasses be converted to sunglasses?
Yes, regular glasses can be converted to sunglasses using clip-on sunglasses, which attach to the front of the glasses, or by using photochromic lenses that darken in sunlight. Another option is to have prescription sunglasses made with the same prescription as your regular glasses. Additionally, some opticians offer lens replacement services, allowing you to switch out your regular lenses for tinted ones.
