What is the perfect example of spherical mirror?
There are two types of spherical mirrors: concave, and convex. These are illustrated in Fig. 68. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors.
What is spherical mirror in short answer?
Solution : A mirror which is made from a part of a hollow sphere is called a spherical mirror. So the inner surface made reflecting it takes a concave mirror on the other hand now if we make the outer surface of the sphere as an application.
What lies on the spherical mirror?
Pole: The center of the reflecting surface of a spherical mirror is called the pole. Centre of curvature (C): The reflecting surface of the spherical mirror forms a part of the sphere. The center of this sphere is called the center of curvature of the mirror.
How spherical mirror are used in daily life?
Spherical mirrors are used in many ways in daily life. Concave mirrors are used by dentists to see enlarged image of tooth. Concave mirrors are also used in vehicles head lights. Convex mirrors are used as rear view mirrors in vehicles because convex mirror increase field of view.
What is the spherical mirror formula?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
What is normal in spherical mirror?
At the point of incidence where the incident ray strikes the mirror, a perpendicular line is drawn is the “Normal”. This normal is what divides the incident ray and the reflected ray equally and gives us the “Angle of Incidence” \theta_i and “Angle of Reflection” \theta_r .
What is spherical mirror formula?
The expression which gives us the relation between these three quantities is called the spherical mirror formula, which is given by: 1v+1u=1f. The mirror formula is applicable for all spherical mirrors for any possible position of the object.
Which lens mirror is used in street light?
Convex mirror is used in street light because it has the property of divergence . Therefore light rays coming from bulb diverges in convex mirror and cover a large distance . In case of a concave mirror ,it has property of convergence .
Why do we use spherical mirrors?
They are used as reflectors in street lamps for diverging light into a larger area. They are placed at the bent of a road or curved roads at hills in order to do surveillance. These mirrors are often known as surveillance mirrors. And the concave mirror is used as the shaving mirror and also used in car’s headlights.
What are the types of spherical mirror?
A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave, and convex.
Which is lens formula?
Let’s see how to use lens formula (1/v-1/u= 1/f) to locate images without having to draw ray diagrams.
Which is an example of a spherical mirror?
Spherical Mirrors. A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave, and convex. These are illustrated in Fig. 68. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors.
Which is an example of hyperbole to express size?
Hyperbole to Express Size. She’s as thin as a toothpick. Her brain is the size of a pea. He was skinny enough to jump through a keyhole. That mall is large enough to have its own zip code. I ate so much on Thanksgiving, I weigh more than a whale. Her smile was a mile wide. His stomach is a bottomless pit.
When do you use hyperbole in a sentence?
In truth, you wouldn’t be able to eat a whole horse. But you use the phrase to show people you’re extremely hungry. Hyperbole is used in literature, rhetoric and everyday speech. You wouldn’t want to use it in nonfiction works, like reports or research papers.
When do you use the hyperbole’it’s too hot’?
This is a common hyperbole used when it is too hot while you are sleeping. The sun usually represents hotness or scorching heat that’s why it feels like you are really sleeping beside the sun when the hot weather is not tolerable.
