when dealing with a flat mirror object-distance and image-distance should be equal.
behind the mirror. The object appears to be behind the mirror
The way light is reflected is different in a concave mirror depending on the position and distance from the object. when light hits the concave mirror when it is near the object, the rays are scattered and it forms a virtual image, i.e it does not come on the screen. the image will be erect and higly magnified. When it is taken further from the object, the image becomes inverted and real, i.e it can be seen on a screen, and will still be magnified.
we see a diminished and virtual image in a convex mirror provided the object is not kept on the focus of the mirror.
A plane mirror forms an erect, virtual image of the same size as the object. As a person gets closer to a plane mirror, the image gets larger.
If our image is real and inverted and smaller than the object ,then it is a concave mirror; if the image is virtual and erect and larger than the object,then it is a convex mirror; if the image is of the same size as of the object,it is a plane mirror. that is how we can distinguish or identify which of the given mirrors are what. BUT if the angle is very small you cannot tell Plane is flat, convex it curves outwards and concave it curves inwards.
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
Characteristics of an image formed by the plane mirror are :- * Virtual and erect (up right ) . * The image is of same size as that of the object . *The image is far behind the mirror as the object is in front of it . *The image is laterally inverted .
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
1. Image is upright 2. Image is virtual 3. Image is of same size as object 4. Image is laterally inverted 5. Distance from object to mirror is equal to the distance from the mirror to the image
image form by plane mirror are virtual,upright,left- right reversed,the same distance from the mirror as the object's distance,and the same size as the object.............that's all
It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.
behind the mirror. The object appears to be behind the mirror
Distance from the mirror, curvature of the mirror.
