What is the image distance from the convex mirror if an object is placed at 20 cm in front of a mirror of focal length 30 cm?

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 .

When an object is kept at a distance of 30 cm from a concave mirror of focal length 20cm?

the image will be formed between f and c , real and inverted , same size of the object.

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? 7.5 cm on the near side.

What is the focal length of a mirror having radius of curvature 20cm?

The radius of curvature of a spherical mirror is 20 cm. What is its focal length? Therefore, the focal length of the spherical mirror is 10 cm.

Is placed at a distance of 20cm?

An object is placed at a distance of 20 cm from a convex mirror or radius of curvature 40 cm. Convex mirror always forms a virtual, erect and diminished image. Therefore, the distance of the image is always less than the focal length and the image always lies between the pole and the focus of the convex mirror.

What will be the position of image formed by a convex lens of focal length 20 cm of an object placed at a distance of 30 cm from it?

A convex lens of focal length 20 cm has a point object placed on its principal axis at a distance of 40 cm from it. A plane mirror is placed 30 cm behined the convex lens. Hence, final image is formed at 10cm in front of plane mirror.

When an object is kept at a distance of 30 cm from a convex mirror?

When an object is kept at a distance of 30 cm from a concave mirror, the image is formed at a distance of 10 cm from the mirror. When an object is kept at a distance of 30 cm from a concave mirror, the image is formed at a distance of 10 cm from the mirror.

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

The images can be enlarged, diminished, and the same size as the object. (Here we take negative signs by applying a new Cartesian sign convention.) 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.

Which mirror is called converging mirror?

concave mirror
A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.

What do you mean by focal length of a spherical mirror is 20cm?

f = 20 / 2. f = 10. Hence, the focal length of the given spherical mirror is 10 cm.

What is the focal length of mirror if radius of curvature is 30 cm?

15cm
So, f = 30/2 = 15cm.

What is the distance of the image from a concave mirror?

If the radius of curvature of a concave mirror is 20 cm and an object is kept at a distance of 15 cm from the concave mirror, what is the distance of the image of the object from the mirror? Use the standard lens formula : 1/U + 1/V = 1/F (ocal point). V = Image distance – the unknown in the equation.

How far are you from your image in a mirror?

How far are you from your image when you stand 0.75 m in front of a vertical plane mirror? A concave mirror with a radius of 20 cm creates a real image 30 cm from the mirror. What is the object distance?

What is the formula to find the distance of a mirror?

The mirror formula is 1 v + 1 u = 1 f, where v, u and f are the distance of the image from the mirror , the distance of the object from the mirror and the focal length respectively. As per the new Cartesian convention, distances from the mirror toward the side of the object are negative and distances toward the other side are positive.

What is the size of image produced by a spherical mirror?

A spherical mirror produces an image has size 5 times greater than the object on a screen, 5 meters away from the object. The mirror is….. The size of the image produced by a convex mirror is always smaller than the size of the object, therefore, the mirror is a concave mirror.
