Does a concave mirror function as a positive lens? Explain. The focal length f is positive for concave mirrors. True False If two concave mirrors are fixed on the opposite sides, what is the focal length of that type of mirror? A concave mirror is placed to the left of a con...
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: ...
Biconvex lens are also known as double convex lens. A biconvex lens means that both surfaces of the lens are convex. Its focal length is positive and mainly for the function of focusing. It is commonly used in imaging relay system and object imaging at finite conjug...
Focal length of convex lens will miximum for (a) blue light (b) yellow light (c) green light (d) red light
True or False: The image reflected from a convex mirror is always virtual, smaller, and upright. True or False: the quantities d i and d o are measured from the lens (or mirror). Which of the following statements are true for refraction in curved surfaces? 1. The focal length for a...
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
What will happen to the focal length of a concave mirror, convex mirror, concave lens and convex lens when immersed in water? will it change ? if yes explain . View Solution Q2 Why focal length of convex mirror and convex lens is positive while concave mirror and concave len...
Know how to match the focal length of the lens to the angle of view you want (that is, how much your lens can capture) and you’ll always feel well equipped. Understanding what focal length is and what it isn’t. When you use a camera lens with a short focal length, such as ...
