What is the power of a concave lens of focal length 15 cm?

Physical Science therefore the power of the lens is 0.067.

When an object is placed at a distance of 15 cm from a concave mirror whose focal length is 10 cm the image will be formed at?

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. Calculate the Focal Length of the Mirror. – Science. 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 type of lens and mirror if focal length is +15cm?

Answer: It’s convex mirror . Because the pole ,focus,focal length &centre of curvature,all are behind the mirror and as we know that when it is behind the mirror it will be positive .

What is the power of a lens of focal length 15 cm?

Are concave lens of focal length 15 cm from an image 10 cm from the lens How far is the object placed from the lens draw the ray diagram?

So, the object is placed 30 cm away from the concave lens. Ray diagram: Was this answer helpful?

Where will the image form if the object is placed 15 cm?

the image will form 15 cm behind the mirror. A plane mirror forms an image of the same size as the object and at the same distance as the object is in front of the mirror.

When an object is placed at a distance of 15 cm from a concave?

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. 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.

When an object is placed at 20 cm from a concave mirror of focal length 10 cm what will be the nature of the image formed?

So, image will be real and inverted .

What is the nature of image formed by a mirror with focal length 15cm?

virtual
An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image. The image is formed behind the mirror and it is virtual.

Which mirror has the focal length of 15?

So, If a mirror has a focal length of -15 cm , then it is a concave mirror.

How far does a concave lens form an image?

A concave lens of focal length 15 cm form an image 10 cm from the lens. How far is the object placed from the lens? Draw the ray diagram also. Hard

What is the focal length of a convex lens?

A convex lens has focal length 20 cm. Calculate at what distance from the lens should the object be placed so that it forms an image at 40 cm on the other side of the lens. State the nature of the image formed. Hard

How far is the object from the lens of 15 cm?

A concave lens of focal length 15 cm form an image 10 cm from the lens. How far is the object placed from the lens? Draw the ray diagram also. A concave lens of focal length 15 cm form an image 10 cm from the lens.

What is the mean value of focal length of concave mirror?

Following is the mean value of the focal length of concave mirror: 10 cm is the focal length of the concave mirror. To get a well illuminated and distinct image of the distinct object, the distant object should be well illuminated. A concave mirror should be always placed near an open window.
