What is a mirror Class 6?
Mirror is an object which reflects light. Shiny and polished surfaces usually act as mirrors. Due to reflection, image of an object is seen in the mirror. Mirror changes the direction of light falling on it.
What is a mirror Class 10?
A mirror is defined as reflecting surface and can be explained by the law of reflection, which states that when a ray of light is made to fall on the reflecting surface, the reflected ray has its angle of reflection, incident ray, and the reflected ray are normal to the surface at a point of incidence.
What is a mirror Class 7?
Spherical Mirror. Spherical Mirror. A curved shining surface of an object acts as a mirror. Most common types of curved mirrors are called spherical mirrors. Spherical mirrors are classified based on their reflective surface as one of two types, concave and convex.
What is Mirror formula?
A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’.
What is a real image class 7?
Class 7 Physics Light. Real and Virtual Image. Real and Virtual Image. When an image is formed on a screen with the help of a mirror, it is called a Real Image. Similarly, an image which can’t be obtained on a screen with the help of a mirror, it is called Virtual Image.
What is concave mirror Class 10?
A spherical mirror, whose reflecting surface is curved inwards, i.e. faces towards the centre of the sphere, is called a concave mirror.
Is concave lens?
A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
Which image is formed in convex mirror?
The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. In this section, let us look at the types of images formed by a convex mirror. When an object is placed at infinity, a virtual image is formed at the focus.
What type of mirror do dentists use?
A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see. Another plus of using a concave mirror is that the image in the mirror isn’t inverted.
Which is used in Periscope?
A periscope is an optical instrument that uses a system of prisms, lenses or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube.
