In this question, the arrangement described suggests that a real image is formed by a lens or optical system where the object consists of a vertical arrow and a horizontal line with a ball.
The characteristics of the image formed are:
- Since the image is real, it will be inverted.
- The image should retain the relative orientation of the object but will be mirrored vertically, as real images formed by a lens are typically inverted.
Therefore, the correct answer corresponds to the image formed where the image is inverted and real.
A transparent block A having refractive index $ \mu_2 = 1.25 $ is surrounded by another medium of refractive index $ \mu_1 = 1.0 $ as shown in figure. A light ray is incident on the flat face of the block with incident angle $ \theta $ as shown in figure. What is the maximum value of $ \theta $ for which light suffers total internal reflection at the top surface of the block ?
