The correct Answer is:
To solve the question, we need to analyze the statements given about the concave lens and determine their validity. ### Step-by-Step Solution: 1. **Understanding the Image Formation by a Concave Lens**: - A concave lens is a diverging lens, meaning it spreads out light rays that are initially parallel (such as those coming from a distant object). - When parallel rays of light enter a concave lens, they diverge after passing through the lens. 2. **Virtual Image Formation**: - The rays that emerge from the concave lens appear to diverge from a point behind the lens. This point is where the virtual image is formed. - Since the rays do not actually converge but only appear to do so when extended backward, the image is virtual. 3. **Analyzing Statement A**: - The statement "The image formed by a concave lens is always virtual" is **true**. This is because a concave lens cannot produce a real image; it only creates virtual images that cannot be projected onto a screen. 4. **Understanding Ray Behavior**: - The second statement discusses the behavior of rays emerging from a concave lens. It states, "The rays emerging from a concave lens never meet on the principal axis." - Since the rays diverge, they do not converge at any point on the principal axis. Instead, they appear to originate from a virtual focus on the same side as the object. 5. **Analyzing Statement R**: - The statement "The rays emerging from a concave lens never meet on the principal axis" is also **true**. The rays diverge and do not converge at any point on the principal axis. 6. **Conclusion**: - Both statements A and R are true, and R correctly explains A. Therefore, the correct option is that both statements are true, and R is the correct reason for A. ### Final Answer: Both statements are true, and R is the correct explanation for A. ---

The image formed by a concave mirror

Assertion:Image formed by concave lens is not always virtual. Reason:Image formed by a lens is real if the image is formed in the direction of ray of light with respect to the lens.

Choose the following statement a True of False. a. The real image formed by a lens is always inverted. b. The image formed by a lens is always inverted. c. The image formed by a concave lens is always erect and diminished. d. An air bubble inside water acts like a concave lens. e. The distance between a real object and its real image formed by a single lens cannot be more than 4f. f. I an object is moved at a constant speed toward a convex lens from infinity to focus, then its image moves slower in the begninning and faster later on, away from the lens. g. The focal length of a glass (mu=1.5) lens is 10 cm in air. When it is completely immersed in water its focal length will become 40cm.

Concave lens is employed to correct

A light ray parallel to the principal axis is incident (as shown in the figure) on a thin planoconvex lens with radius of curvature of its curved part equal to 10 cm. Assuming that the refractive index of the material of the lens is 4//3 and medium on both sides of the lens is air, find the distance of the point from the lens where this ray meets the principal axis. Find your answer in the form (X)/(7)cm and fill value of X .

Assertion:A convex lens and a concave lens are kept in contact. They will behave as a diverging lens if focal length of convex lens is more. Reason: Power of a concave lens is always less than the power of a convex lens, as power of concave lens is negative whereas power of convex lens is positive.

A real image is formed by a convex lens. Then it is put in contact with a concave lens and again a real image is formed. This image will shift towards the lens system shift away from the lens system remain in its original position shift to infinity

The size of the image of an object, which is at infinity, as formed by a convex lens of focal length 30 cm is 2 cm. If a concave lens of focal length 20 cm is placed between the convax lens and the image at a distance of 26 cm from the convex lens, calculate the new size of the image.

Name the lens that always forms a virtual and erect image.

A point source of light is placed on the principal axis between F and 2F of a concave lens. On the other very far , a screen is placed perpendicular to principal axis. As the screen is brought close towards lens
