Key Concepts

Mirror Equation

The mirror equation, given by 1/f = 1/do + 1/di (where f is the focal length, do is the object distance, and di is the image distance), mathematically relates the positions of the object and image for a curved mirror. This equation is essential for predicting how the image shifts as the object is moved.

Image Movement (Parallax)

When an object is moved relative to a mirror, the corresponding real image also shifts due to the mirror geometry and the laws of reflection. In the context of a concave mirror, moving the object farther from the mirror (to the left) typically causes the image to move in the opposite direction (to the right) when viewed from the original perspective. This relative motion is often explained through the concept of parallax.

Concave Mirror

A concave mirror is a spherical mirror that curves inward like a bowl and converges light rays. It forms images whose characteristics (real or virtual, magnified or reduced) depend on the object's position relative to the focal point. This concept is fundamental in understanding image formation by curved mirrors.

Focal Point

The focal point of a concave mirror is the point where parallel rays of light converge after reflection. Its distance from the mirror, known as the focal length, is crucial in determining the nature and location of the image. The relationship between the object distance and the focal length governs whether the image is real or virtual.

Transcript

00:01 So given in the question an object is placed to the left of a concave mirror beyond the focal point in what direction left or right will the image move when the object is moved further to the left when an object is placed beyond the focal point of the concave mirror the image formed is always real and inverted so for an object placed beyond the focal point of a concave mirror the image formed and a is real and inverted.

00:40 When an object, when that object is moved farther to the left, when the object is more further to the left, that is far away from the concave mirror, far from the concave mirror, starting from its focal point or starting beyond the focal point, the image formed will come closer and closer to the concave mirror.

01:24 Mirror that is the image will move to the right of the concave mirror will move to the right of the concave mirror of the concave mirror.

01:50 Now this can be explained by considering the following cases.

02:08 Case 1.

02:11 When the object is placed between the focal point f, f, and the center of curvature c then the image is formed between infinity and the center of curvature c.

02:43 Between infinity and the center of curvature c.

02:52 So in the diagram considering a concave mirror and the object a, b placed between beyond the focal point and before the center of curvature.

03:07 So a ray parallel to the principal axis will pass to the focus.

03:11 The other one at the pole of the mirror will pass and delete will reflect back.

03:19 So the image will form beyond c and that is as shown in the diagram...
