Real Image Formation by Convex Lens – Rankers Physics

Refraction by Spherical Surfaces: Practice Problem & Solution

Assertion (A): If an object is placed between (f) and (2f) of a convex lens, a real image can be seen on a screen placed at image location. If the screen is removed then image will not be seen. Reason (R): Real image of a object can not formed in air.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Refraction by Spherical Surfaces. Understanding the underlying formula is key to arriving at the correct answer below:

A real image is formed by the actual intersection of light rays and exists in space independently of a screen. It can be viewed by the eye even without a screen. Real images are formed in the medium where rays converge, typically air. Therefore, both assertion and reason are false.

2. Assertion (A): The Snell's law \(\mu sin \theta = \text{constant}\) is valid at different boundaries irrespective of the shape of the boundaries. Reason (R): When light enters from vacuum into a medium of refractive index \(\mu\), its speed and wavelength increases by \(\mu\).  
3. Assertion (A): For observing a rainbow, sun should be shining in one part of the sky and it is raining in the opposite part of sky, and observer should stand with his back towards raining side. Reason (R): Rainbow appears due to directly reflection of sunlight from water drops of rain.  
4. Assertion (A): Minimum distance between a real object and its real image formed by a convex lens is three times the focal length of lens. Reason (R): Distance between an object and its real image formed by convex lens is minimum when magnification produced by the lens has minimum value.
