Is the law of reflection applicable to all mirrors?
It is a fact that laws of reflection are applicable to all reflecting surfaces.
Is law of reflection valid for all kind of mirror?
The laws of reflection hold good for all the mirrors irrespective of their shape (i.e. flat or curved). The angle of incidence=angle of reflection. Even the curved mirrors (concave and convex) do follow this law.
What is the normal in the law of reflection?
This line is known as a normal line (labeled N in the diagram). The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
What is the use of spherical mirror?
Uses of Spherical Mirrors They form upright, enlarged images, and are therefore useful in makeup application or shaving. They are also used in flashlights and headlights because they project parallel beams of light, and in telescopes because they focus light to produce greatly enlarged images.
What is the radius of curvature of the mirror?
How far is this converging point from the mirror’s surface if the radius of curvature (R) of the mirror is 150 cm? If the radius of curvature is 150 cm. then the focal length is 75 cm….The Anatomy of a Curved Mirror.
| Principal axis | Center of Curvature | Vertex |
|---|---|---|
| Focal Point | Radius of Curvature | Focal Length |
Is the focal length of concave mirror positive or negative?
| focal length | object distance | |
|---|---|---|
| concave mirror | positive | positive |
| convex mirror | negative | positive |
| converging lens | positive | positive |
| diverging lens | negative | positive |
