Which type of reflection is produced when light reflects from curved and smooth surfaces?
Show Hint
In convex reflection, light rays diverge, while in concave reflection, they converge.

- Concave reflection
- Convex reflection
- Diffused reflection
- None of these

The Correct Option is B
Solution and Explanation
When light reflects off curved and smooth surfaces, particularly from a convex surface, the light rays diverge after reflection. This is called convex reflection. In contrast, concave surfaces cause light rays to converge.
Convex surfaces are those that curve outward, like the surface of a sphere, which results in light spreading out after reflection.

- A thin convex lens of focal length \( 5 \) cm and a thin concave lens of focal length \( 4 \) cm are combined together (without any gap), and this combination has magnification \( m_1 \) when an object is placed \( 10 \) cm before the convex lens.
Keeping the positions of the convex lens and the object undisturbed, a gap of \( 1 \) cm is introduced between the lenses by moving the concave lens away. This leads to a change in magnification of the total lens system to \( m_2 \).
The value of \( \dfrac{m_1}{m_2} \) is

- A convex lens of refractive index \(1.5\) and focal length \(f=18\) cm is immersed in water. The difference in focal lengths of the given lens when it is in water and in air is \( \alpha \times f \). Find the value of \( \alpha \). (Given: refractive index of water \(=\dfrac{4}{3}\))
- Given below are two statements: Statement I: A plane wave after passing through a prism remains a plane wave, but passing through a small pin hole may become a spherical wave. Statement II: The curvature of a spherical wave emerging from a slit will increase for increasing slit width. In the light of the above statements, choose the correct answer:
