Question

Mark ‘T’ if the statement is true and ‘F’ if it is false: A real image cannot be obtained on a screen. (T/F)

• A. True
• B. False

Answer 1

The correct option is B False

Reflection

1. Reflection is a phenomenon of light in which when a light ray hits a surface it deflects its direction and propagates back in a different path.
2. The first law of reflection is that the incident ray, reflected ray, and the normal of the reflection all lie on the same plane.
3. The second law of reflection is that the angle of incidence is equal to the angle of reflection

Refraction

1. Refraction is defined as the phenomenon of bending light when it travels from one medium to another medium.
2. The first law of refraction states that the incident ray, the refracted ray, and the normal all lie on the same plane.
3. The second law of refraction, also known as Snell's law states that the refractive index of a medium is defined as the ratio of the sine of the angle of incidence and sine of the angle of refraction.

Image

1. The image formed by a mirror or a lens is of two types.
2. Real image: The image that is formed due to the actual divergence or intersection of the reflected or refracted rays is called a real image. Therefore, a real image can be obtained on a screen.
3. Virtual Image: The image that is formed by the tracing back of the converged ray and the traced rays are found to diverge at a point. Hence, this image cannot be obtained on a screen.

Hence, the given statement is false.
