What distance from a concave mirror of focal length is 30cm?

∴ distance between two positions = 45 – 15 = 30 cm.

At what distance from a concave mirror of focal length 30cm should an object be placed so that the image is magnified 3 times?

Physical Science Thus the object should placed 20 cm from the front of mirror.

What is the magnification produced in case of a concave mirror of focal length 10 cm if object is placed at Centre of curvature?

– 1
(a) The object must be at the centre of curvature of concave mirror. The image formed is real, inverted and of the same size as the object. That is why magnification = – 1.

When an object is placed at 30 cm in front of a concave mirror image of the same size is formed what is the focal length of the mirror?

Here v is the image of an object and the image formed by the concave mirror is at 30cm in front of it. Therefore the image is real and inverted. Thus correct option is (D).

Where should an object be placed in front of a concave mirror of focal length 30cm so as to obtain real image two times magnified?

Answer: magnification “m”=-2times. 40+2u=-20. so if you object be placed at the distance of 30 cm then the two times magnified image will be obtain.

When an object of is placed 30 cm in front of the mirror the magnification obtained is 3 times at what distance from the mirror will the image be formed?

Hence, the object should be placed at a distance of 60cm in front of a convex to get the magnification of 1/3.

At what distance from a convex mirror of focal length 30cm should an object be placed so that its image is formed 20cm from the mirror on the other side?

An object is placed at a distance of 30 cm from a convex lens of focal length 20 cm. Image distance, v =? v=60010=60 cm .

What is the magnification produced by a concave mirror of focal length 10cm?

For a concave mirror of focal length 10 cm, magnification of a real image is 3. The image distance is (A) 10 cm (C) 30 cm (B) 20 cm (D) 40 cm 41. Image produced by a concave mimor liar.

What is the magnification of the concave mirror?

In a concave mirror, when the distance of the object is less than the focal length, the magnification will be greater than one. When the distance of the object is greater than the focal length, then the magnification is less than one.

Where is the image located When an object is placed 30 cm from a concave lens with a focal length of 10 cm?

A diverging lens has a focal length of 10 cm. Where is the image located when an object is placed 30 cm from the lens? 30 cm on the near side.

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

When an object is placed 20 cm from a concave mirror, a real image magnified three times is formed. Find: (a) the focal length of the mirror. ( b) Where must the object be placed to give a virtual images three times the height of the object?

What is the image formed by a convex mirror of focal length?

The image formed by convex mirror of focal length 30cm is the quarter of size of the object. Then the distance of the object from the mirror is, The Fish Tale Across the Wall Tenths and HundredthsParts and Whole Can you see the Pattern?

Which mirror produces three times magnified enlarged real image?

A Concave Mirror Produces Three Times Magnified Enlarged Real Image Of An Object Placed At 10 Cm In Front Of It Where Is The Image Located A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located? The magnification (m) is given as = -3 (as image is real)

How do you find the distance of an image from a mirror?

We use the thin lens equation 1/f = 1/di+1/do, where f is the focal length, di is the image distance, and do is the object distance. Solving for di, we get 60. The distance of the image from the mirror is 60 cm.
