When an object is placed at a distance of 50cm?

When an object is placed at a distance of 50 cm from a concave spherical mirror the magnification produced is - (1/2). When an object is placed at a distance of 50 cm from a concave spherical mirror, the magnification produced is .

Keeping this in consideration, when an object is placed at a distance of 50 cm from a convex lens?

When an object is placed at a distance of 50 cm from a convex lens, an image of same size as the object is formed.

Similarly, when an object is placed at a distance of 50 cm from a concave mirror the magnification produced is? When an object is plced at a distance of 50cm from a concave sperical mirror, the magnification produced is, 1/2.

Subsequently, one may also ask, when an object is placed at a distance of 60cm?

When an object is placed at a distance of 60 cm from a convex mirror, the magnification produced is 1/2.

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

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. The negative sign shows that the mirror is concave.

When an object is kept at any distance in front of a concave lens the image formed is always?

A concave lens always forms a virtual, erect and diminished image.

What is the power of a concave lens of focal length 25 cm?

Power is expressed as the inverse of focal length, where a focal length of 1 meter is equal to one diopter. So a 25 cm. focal length (0.25 meters) has a power of 4 diopters.

WHAT IS lens power?

If a lens has a shorter focal length it is said to be more powerful. The power of a lens is defined as the reciprocal of the focal length. Lens power is measured in dioptres (D). Diverging (concave ) lenses have negative focal lengths, so they also have negative power values.

How do you find the focal length?

The lens equation says 1/f = 1/Do + 1/Di, where f is the focal length of the lens, Do is the distance from the object to the lens and Di is the distance from the lens to the in-focus projected image.

How do you determine magnification?

Working out magnification:

Measure the scale bar image (beside drawing) in mm.
Convert to µm (multiply by 1000).
Magnification = scale bar image divided by actual scale bar length (written on the scale bar).

When the object is placed between F and 2f of a convex lens the image formed is?

When an object is placed between F and 2F in front of a convex lens, the image formed is magnified, real, inverted and beyond 2F.

What is the lens formula?

Derivation of Lens Formula

Let F be the principle focus and f be the focal length. An object AB is held perpendicular to the principal axis at a distance beyond the focal length of the lens. A real, inverted magnified image A'B' is formed as shown in the figure. The above equation is known as the Lens formula.

When an object is placed 60cm from a converging lens?

Question: When An Object Is Placed 60 Cm From A Converging Lens It Forms A Real Image. When The Object Is Moved To 40 Cm From The Lens The Image Moves 10 Cm Farther From The Lens.

At what distance should an object be placed from a convex lens?

Using lens formula to find the position of object u. Therefore the object must be placed at a distance of 72 cm from the focal length of the lens. And the magnification of the image formed will be inverted this could be seen by the negative sign obtained.

When an object is placed at a distance of 60 cm from a diverging spherical mirror?

When an object is placed at a distance of 60cm from a diverging spherical mirror, the magnification produced is 0.5.

When object moves closer to a concave lens the image by it shift?

when an object moves closer to a concave lens the image formed by it shifts away from the lens , it forms real image as we move closer to lens.

Between which two points of a concave mirror should an object be placed to obtain magnification of?

Between which two points of a concave mirror should an object be placed to obtain a magnification of -3? Solution : For m = - 3, the image is real, inverted and enlarged. The object must be placed between F and C of the concave mirror.

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

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

Question By default hide Solutions

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 40 cm from a concave spherical mirror?

When an object is placed at a distance of 40 cm from a concave spherical mirror, the magnification produced is 1/2, where should the object be placed to get a magnification of 1/32 Ans.
