Which Man's Reflection is This in The Mirror? #shorts | Logic puzzle game | Brain Teaser | Paheliyan

A point sources of light is 60cm from a screen and is kept at the focus of a concave mirror which reflect light on the screen .the focal length of the mirror is 20cm The ratio of average intensities of the illiumination on the screen when the mirror is present and when the mirrror is removed is:

A boy of height H is standing in front of a mirror, which has been fixed on the ground as shown in figure. What length of his body can the man see in the mirror? The length of the mirror is (H//2) .

(a) To construct a ray diagram, we use two rays which are so chosen that it is easy to know their directions after reflection from the mirror. List two such rays and state the path of these rays after reflection in case of concave mirrors. Use these two rays and draw ray diagram to locate the image of an object placed between pole and focus of a concave mirror. (b) A concave mirror produces three times magnified image on a screen. If the object is placed 20 cm in front of the mirror, how far is the screen from the object?

The reflecting surface of a plane mirror is vertical. A particle is projected in a vertical plane which is also perpendicular to the mirror. The initial speed of the particle is 10m//s and the angle of projection is 60^@ from the normal of the mirror. The point of projection is at a distance 5m from the mirror. The particle moves towards the mirror. Just before the particle touches the mirror, the velocity of approach of the particle and the image is:

A man moves on the path AB. He wants to see the image of the object kept at a perpendicular distance 2d apart from the path. The rays after reflection from the mirror fall on the path as shown. The man can see the image if he runs through the distance x on the path. If the length of the mirror is 4m, find the value of x (in m).

In the diagram shown below, a light ray is incident on a convex mirror. Through which point will the ray travel after reflecting off the mirror?
