What type of image is formed by a concave mirror when an object is placed at a distance about 70 cm from a concave mirror?
This means that the image formed will be real and inverted in nature.
When an object is placed at the distance of 27cm from concave mirror of focal length 18 cm image will be formed at?
General Science Thus, the image is formed at the distance of 54 cm in the front of concave mirror.
When the image is at a distance of 10 cm from the pole the image should be?
What is the nature of image formed when an object is held at a distance of 10 cm from the pole of a concave mirror of focal length 15 cm? The object lies between pole and principal focus of concave mirror. Therefore, the image formed is virtual, erect and magnified.
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 height of the mirror image?
The image height is 10 cm. The positive sign indicates that the image is real or the image is 20 cm in front of the mirror, on the same side as the object. The negative sign means the image is inverted. The plus sign indicates that the image is real or the image is 15 cm in front of the mirror, on the same side as the object.
How do you find the distance between an image and object?
The distance between object and image = 5 meters. Solution : 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. Object distance (d) = x. Image distance (d’) = x + 5. Image magnification (M) = 5 times.
How can a real image form behind a mirror?
Since the mirror produces three times magnified image, the image must form at a distance three times the original distance (object distance, u) so v must be three times u. Since it is a real image, it has to form on the same side as the object. Real image can not form behind the mirror. Solving it by exact formula.
