When an object is placed at a distance of 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 60 cm from a concave mirror the magnification produced is 1 by 2 Where should the object be placed to get a magnification of 1 by 3?
∴ Object should be placed at 120cm.
When an object is placed at a distance of 25 cm from a mirror the magnification is M1?
When an object is placed at a distance of 25cm from a mirror, the magnification is M1 the object is moved 15cm for the away with respect to the earlier position, the magnification become M2.
When an object is placed at a distance of 15 cm from a concave 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 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 60 cm from convex mirror what is the magnification produced is 1 2?
When an object is placed at a distance of 60cm from the convex mirror the magnification produced is 0.5.
When an object is placed at a distance of 50 cm from a concave spherical mirror the magnification?
When an object is plced at a distance of 50cm from a concave sperical mirror, the magnification produced is, 1/2.
When an object is placed at 2f1 of a convex lens?
Explanation: If object placed at 2F same size as the object image formed at 2F2. Image formed is real and inverted.
When an object is placed at a distance of 30 cm from a convex mirror the magnification of 1/2 Where should the object be placed to get the magnification of 1 What is the focal length of the mirror?
Hence the object should be placed at a distance of \(60\ cm\) in front of a convex mirror to get the magnification of \(\frac{1}{3}\).
At what distance does a concave mirror focal length 20cm?
Thus, the distance of the object from the mirror is equal to 10cm. Hence, the correct answer is option C.
When an object is placed 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 placed at a distance of 30 cm from a concave mirror?
Explanation:Now since the object is placed on 30 cm . It means the object is placed at 2f because f=15cm . In this case when the object is placed at 2f the image in concave lens will form b/w f and o .
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 30cm?
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 position of the image when an object is placed at a distance of 30cm from a concave mirror of focal length 30cm?
Answer. the image will be formed between f and c , real and inverted , same size of the object.
When an object is placed at a distance of 30 cm from a concave mirror of radius of curvature 30 cm What is magnification of image formed and what is its nature?
from a concave mirror. The magnification produced is 1/2.
What is the mirror formula?
Let’s explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.
When an object is placed 30 cm in front of a concave mirror image of the same size is formed what is the focal length of the mirror?
Thus, the screen should placed at 30 cm in front of the mirror so as to obtain the real image. The image is real, inverted and of the same size as the object. The image formation is shown in the ray diagram given below. An object of size 7.0 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm.
What is the nature of the image formed by a concave mirror if the magnification is 3?
What is the nature of the image formed by a concave mirror if the magnification is 3. Since the value of magnification has a positive value the image formed will be virtual and erect. Here the value of the magnification is +3, therefore, the image that will be formed will be virtual and erect.
What type of image is formed in a plane mirror?
virtual image
What is the minimum number of rays required to locate an image?
two rays
What is the minimum number of rays required to locate an image in concave mirror?
two
How many rays do you need to draw in order to find the image created by a curved mirror?
What happens when an object is at the focal point of a concave mirror?
Reflection from a Concave Mirror When the object is that the focal point, the image is at infinity. As the object moves towards the mirror inside the focal point the image becomes virtual and upright behind the mirror.
