प्रश्न
Find out the letters of English alphabet or any other language known to you in which the image formed in a plane mirror appears exactly like the letter itself. Discuss your findings.
उत्तर १
If English letters like A, H, I, M, O, T, U, V, W, X and Y are placed in front of a mirror, then their images look exactly like the letters. These letters are vertically symmetrical. If we divide these letters from the middle, then their right and left parts will look the same.
उत्तर २
The letters of the English alphabet give exactly the same image in a plane mirror like the letter itself:
A, H, I, M, O, T, U, V, W, X, Y

Define Radius of curvature of the spherical mirror
A diverging lens is used in:
(a) a magnifying glass
(b) a car to see objects on rear side
(c) spectacles for the correction of short sight
(d) a simple camera
A 50 cm tall object is at a very large distance from a diverging lens. A virtual, erect and diminished image of the object is formed at a distance of 20 cm in front of the lens. How much is the focal length of the lens?
Write the spherical mirror's formula and explain the meaning of each symbol used in it.
Answer the following question:
Distinguish between the convex mirror and the concave mirror.
Answer the following question.
Write the modification in the curvature of the eye lens which enables us to see the nearby objects clearly?
What is the relationship between the focal length and radius of curvature?
The following figure shows a concave mirror with its pole (P), focus (F), and center of curvature (C). Draw a ray diagram to show the formation of the image of an object AB by the concave mirror.
The diagram below shows the parallel rays incident on a convex mirror. C is the centre of the curvature of the mirror. By drawing the paths of the reflected rays, label the focus F and hence find the focal length of the mirror.
What is “aperture”?
