When an object is placed at a distance of 20cm infront of a concave mirror of focal length 15cm then the image formed by the concave mirror is?

Solution: Thus, the object will be formed at -60cm on the same side of the mirror where object is kept.

What is the position of the image when an object is placed at a distance of 20 cm from a concave mirror of focal length 15 cm?

u = -20 cm,f = 15 cm. Nature of the image: Virtual.

What will be the position of image if an object is placed at a distance of 25 cm from a concave mirror of focal length 15 cm?

v = the distance of the image from the mirror, u = the distance of the object from the mirror. ⇒ Image distance (v) = -10 / 375 = – 37.5 cm. So option 4 is correct.

When an object is placed 20cm away from a concave mirror?

When an object is placed 20 cm from a concave mirror, a real image magnified three times is formed.

When an object is placed at a distance of 25 cm from?

When an object is placed at a distance of 25 cm from a mirror, the magnification is m1. The object is moved 15cm farther away with respect to the earlier position, and the magnification becomes m2. If m1/m2=4 , then calculate the focal length of the mirror.

When an object is placed 20cm from a converging mirror?

When an Object is Placed 20 Cm from a Concave Mirror, a Real Image Magnified Three Times is Formed.

What is the distance in front of a concave mirror?

An image an by a concave mirror is 4 times greater than the object. If the radius of curvature 20 cm, determine the object distance in front of the mirror! The object distance = 12.5 cm. 4. A 1-cm high object is placed 10 cm from a concave mirror with the focal length, f = 15 cm. Determine :

What is the image formed at a distance of 15 cm?

When an object is placed at a distance of 15 cm from a concave mirror, its image is formed at 10 cm in front of the mirror. What is the focal length of the mirror? f is the focal length of the mirror.

What is the sign for object distance image distance and focal length?

1/v + 1/u = 1/f where u, v, f are object distance, image distance, and focal length respectively. What is the sign for object distance, image distance, and focal length for a concave/convex lens? the object distance is -ve. image distance is +ve for real image and -ve for virtual image. focal length is +ve. focal length is -ve.

What distance from the mirror should a screen be placed?

An object of size 7.0 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm. At what distance from the mirror should a screen be placed, so that a sharp focused image can be obtained? Find the size and the nature of the image. The screen must be placed at a distance of 54 cm from the mirror in front of it.
