How many cases does a concave mirror have?
Case 1: the object is located beyond the center of curvature (C) Case 2: the object is located at the center of curvature (C) Case 3: the object is located between the center of curvature (C) and the focal point (F) Case 4: the object is located at the focal point (F)
What is the case of concave mirror?
Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.
What are the two cases of convex mirror?
There are only two possibilities of position of object in the case of a convex mirror, i.e. object at infinity and object between infinity and pole of a convex mirror. Object at infinity: When the object is at the infinity, a point sized image is formed at principal focus behind the convex mirror.
Is concave mirror real or virtual?
Concave mirrors can produce both real and virtual images depending on the distance from the mirror to the object and the curvature of the mirror, while convex mirrors produce only virtual images.
What is concave mirror Class 10?
1)Concave Mirror:A spherical mirror whose reflecting surface is curved inwards ie faces towards the centre of sphere.
What are the rules for image formation in case of concave mirror?
For concave mirrors, when the object is between F and C, the image will be beyond C and will be enlarged and inverted. For concave mirrors, when the object is between F and the mirror, the image will be behind the mirror and will be enlarged and upright.
Why are there only 2 cases in convex mirror?
What are examples of concave mirrors?
The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc.
What are the image characteristics of a concave mirror?
Image Characteristics for Concave Mirrors. That is to say, if the object is right side up, then the image is upside down. In this case, the image is reduced in size; in other words, the image dimensions are smaller than the object dimensions. If the object is a six-foot tall person, then the image is less than six feet tall.
How many incident rays are in a concave mirror?
Of the five incident rays drawn, two of them correspond to the incident rays described by our two rules of reflection for concave mirrors. Because they are the easiest and most predictable pair of rays to draw, these will be the two rays used through the remainder of this lesson.
Which is the best description of a spherical mirror?
Spherical Mirrors A plane mirror is a flat, smooth reflective surface. A plane mirror always forms a virtual image that is upright, and of the same shape and size as the object, it is reflecting. A spherical mirror is a mirror that has a consistent curve and a constant radius of curvature.
How are the distances measured from the pole of a mirror?
The normally used convention is the Cartesian sign convention. According to this convention, all the distances are measured from the pole of the mirror, i.e. the pole (P) of the mirror is assumed as the origin. The principal axis of the mirror is taken as the x-axis of the coordinate system. The conventions are as given below:
