A convex mirror of focal length f forms an image which is 1n times the object. The distance of the object from the mirror is View Solution Q3 A concave mirror of focal length f produces an image n times the size of the object. If the image is real, then the distance of the object...
Light from the object passes rightward through the lens, reflects from the mirror, passes leftward through the lens, and forms a final image of the object. View Solution Q3 A converging lens of focal length f1 is placed in front of and coaxially with the convex mirror of focal ...
To solve the problem of determining the power of a combination of a convex lens and a concave lens, we can follow these steps: 1. Identify the Focal Lengths: - The focal length of the convex lens (f1) is +30 cm (positive because it is a convex lens). - The focal length of the...
An object is at a distance of 20 m from a convex lens of focal length 0.3 m. The lens forms an image of the object. If the object moves away from the lens at a speed of 5 m/s, the speed direction of the image will be:
To solve the problem, we need to find the new focal length of a convex lens when it is immersed in a liquid with a different refractive index. Here's the step-by-step solution: Step 1: Understand the relationship between focal length and refractive indexThe focal length f of a lens is...
In the experiment of finding the focal length of a convex lens, we should use: A. A ruler and a white paper B. A protractor and a mirror C. A ruler and a concave lens D. A protractor and a white paper 相关知识点: 试题来源: ...
State the relation between object distance, image distance and focal length of a spherical mirror (concave mirror or convex mirror). Calculate the image distance for an object of height 12 mm at...
A concave mirror produces a virtual image that is 9 times as tall as the object. If the object is 38 cm in front of the mirror, what is the focal length of this mirror? (in units of cm) 1) An object is 24 cm away from a ...
