Draw a diagram to find the focal length of a concave mirror by using distant object also write down the formula used.
Important Questions on Light - Reflection and Refraction
Three students measured the focal length of a convex lens using parallel rays from a distant object. All of them measured the distance between lens and the inverted image of the screen. Student saw a sharp image on the screen and labelled the distance as .
Student saw a slightly larger blurred image on the screen and labelled the distance as .
Student saw a slightly smaller blurred image on the screen and labelled the distance as .
What relation most likely would be between the three measurements?
Parallel rays from a distant tree incident on a device 'X', form its distinct image on a screen as shown. What is the device 'X' and which of the following diagrams correctly shows the image of the tree on the screen?
What precautions should be taken for the experiment to determine the focal length of convex lens by obtaining image of a distant object.
The figure shown below, the formation of an image by a convex lens on the white screen. Which distance represent the focal length of the lens?
In performing the experiment using a convex lens, you find sharp and clear image of a distant object on a screen as shown in the following figure. If you move the screen to the right side then what will you observe about the nature of the image?
