What is the position of the image when an object is placed at a distance of 30 cm from a concave mirror of focal length 30 cm? The image is formed on same side of the object. Explanation:Now since the object is placed on 30 cm . It means the object is placed at
2f because f=15cm
.
When an object is placed at 30 cm in front of a concave mirror image of same size is formed what is the focal length of the mirror?
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
.
When an object is kept at a distance of 30cm from a concave mirror?
If the object distance (u) is 30 cm and image distance (v) is also 30cm. Then,
f=15cm
. Hope you got your answer.
When an object is kept at a distance of 30 cm from a convex lens?
A point object O is kept at a distance of 30 cm from a convex lens of power +4D towards its left. It is observed that when a convex mirror is kept on the right side at a distance of 50 cm from the convex lens, the image of the object O formed by the lens-mirror combination coincides with the object itself.
When the object is kept at 30 cm from the concave mirror of focal length 15 cm What is the image formed at ?
Image is formed
at Centre of Curvature
.
When an object is kept at a distance of 20cm from a concave mirror?
When an object is kept at a distance of 20 cm from a concave mirror, the image is formed at a distance of 10 cm. If the object is moved with a speed of 4 m/s, the speed with which the image moves is us-20 (A) 10 cm/sec (B) 1 m/sec (C) 4 m/sec (D) 0.4 m/sec.
When an object is kept at a distance of?
An object is kept at a distance of 16 cm from a thin lens and the image formed is real. If the object is kept at a distance of 6 cm from the same lens, then the image formed is virtual. If the sizes of the image formed are equal, then the focal length of the lens will be. (A) 15 cm.
When an object is held very close to a concave mirror the image is?
Answer: Concave lens forms image behind the mirror , thus producing
a Virtual and Upright image
. From concave lens virtual ,inverted and small image is formed.
What is the minimum number of rays required to locate an image?
A minimum of
two rays
are required for locating the image of an object formed by a concave mirror. When an object is placed between the focus and the pole of a concave mirror, a virtual image is formed (ray diagram for the same is given below). image.
What would be the size of the image formed if the object is 2 cm high?
The size of the image formed if the object is 2 cm high is
the same as that of the size of the object
.
When an object is kept at a distance of 30?
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. If the object is moved with a speed of 9 m sā1, the speed with which image moves is.
When an object is kept within the focus of a concave mirror?
When an object is kept within the focus of a concave mirror,
an enlarged image is formed behind the mirror
. The nature of the image is : When an object is kept within the focus of a concave mirror, an enlarged image is formed behind the mirror.
How far is a concave mirror from focal length 20cm?
Thus, the distance of the object from the mirror is equal to
$10cm
$. Hence, the correct answer is option C.
What is the position of the image when an object is placed at a distance of 30 cm from a concave mirror of focal length 30 cm?
Complete step by step answer: A concave lens is a diverging lens. Unlike converging lenses, the images formed by the concave lens are
always located on the side of the object, virtual, upright and smaller in size
than the object. So, the image is produced at 15 cm from the lens' optical centre.
What is the magnification of an object placed 30 cm from a concave mirror of focal length 15 cm?
from a concave mirror. The magnification produced is
1/2
.
At what distance from a concave mirror of focal length 30cm should an object be placed?
Substitute, v=ā15cm, u=ā30cm and h1=5cm to find the value of h2. Therefore, the object should be placed 30 cm from the optical centre and the size of the image formed is
2.5 cm
. Additional information: The distance between focal point and lens is called focal length.
