What is the nature of the mirror having a magnification of?
Magnification is defined as ratio of height of image to the ratio of height of object. It is a concave mirror which has magnification denoted by the sign minus. Nature of the mirror is real and inverted.
How far from a convex lens of focal length 20cm would you place an object to get a real image and last three times?
u= -2 x 20/3 = -40/3 cm. u= -2 x 20/3 = -40/3 cm. Answer: Between the centre of the curvature and its focus, if the image is real.
How far from a convex lens of focal length 20cm would you place an object to get an image and last three times?
Answer. u= -2 x 20/3 = -40/3 cm.
How far should an object be placed from a convex lens of focal length 20cm would you place an object to get an image enlarged 3 times?
Object distance from convex lens and height of the image. An object should be placed at distance 60 cm from the convex lens.
How far from a convex lens of focal length 20cm would you place an object?
therefore the two positions of the object are:-80/3 cm and -40/3 cm. If You’re Satisfied With The Ans So Plzz Mark It As The Brainliest..
Where should an object be placed from a converging lens of focal length 20cm so as to obtain a real image of magnification?
A convex lens of focal length 20 cm forms a real and magnified image when the object is placed between 20 cm and 40 cm.
At what distance from the object should the lens be placed?
72 cm
Where should you place an object in front of a converging lens in order to obtain a real image?
A converging lens produced a virtual image when the object is placed in front of the focal point. For such a position, the image is magnified and upright, thus allowing for easier viewing.
Does a convex lens produce an inverted image?
A convex lens makes objects look larger because it disperses light. The image appears inverted and smaller when the light is focused at a point beyond the lens’s focal length.
What will be the position of an image formed if an object is kept at 10 cm in front of a concave mirror of focal length 20cm?
hence, image position is the 20cm right side from the pole of the concave mirror as shown in the diagram. The image is straight and bigger than the object.
What is the position of image when object is placed at a distance of 10cm?
Solution. Therefore, the position of image will be at infinity.
