Weekly Quiz Competition

Question 1
1 / -0

When a ray of light from air enters a denser medium, it

A
bends away from the normal

B
bends towards the normal

C
is reflected back

D
goes undeviated
Question 2
1 / -0

The ray of light, which suffers bending, is called

A
incident ray

B
reflected ray

C
refracted ray

D
emergent ray
Question 3
1 / -0

Which of the following has the highest refractive index?

A
Water

B
Glass

C
Ruby

D
Diamond
Question 4
1 / -0

Which of the following statements is incorrect?

A
Power of a lens is reciprocal of its focal length.

B
Convex lens is also called a diverging lens.

C
A real image is inverted with respect to the object.

D
Our eye lens is a convex lens.
Question 5
1 / -0

A lens forms an inverted image of an object. What kind of lens is it?

A
Concave

B
Convex

C
Either (1) or (2)

D
None of these
Question 6
1 / -0

When a white light ray falls on a hollow prism, then

A
the light emerging from the prism gives spectrum, but the bending of all colours is away from the base

B
the light emerging from the prism gives spectrum and all the colours bend towards the base, with violet bending the most and red bending the least

C
the light emerging from the prism gives no dispersion

D
the light emerging from the prism gives spectrum and all the colours bend towards base, with violet bending the least and red bending the most

Solution

When a white light ray falls on a hollow prism, then the light emerging from the prism gives no dispersion because surface and hollow prisms behave like slabs and thus, there is no dispersion.
Question 7
1 / -0

Which colour gets refracted the most while passing through a prism?

A
Violet

B
Red

C
Blue

D
Orange

Solution

Violet colour gets refracted the most while passing through a prism. The lesser is the wavelength, the greater is the angle of deviation.
Question 8
1 / -0

Which phenomenon gives rise to Tyndall effect?

A
Reflection of light

B
Refraction of light

C
Scattering of light

D
Dispersion

Solution

The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension.
Question 9
1 / -0

The clear sky appears blue because

A
blue light gets absorbed in the atmosphere

B
ultraviolet radiations get absorbed in the atmosphere

C
light of violet and blue colours gets scattered more than the light of all other colours by the atmosphere

D
light of all other colours is scattered more than the light of violet and blue colours by the atmosphere

Solution

The clear sky appears blue because light of violet and blue colours gets scattered more than the light of all other colours by the atmosphere.
Question 10
1 / -0

Which of the following statements is correct?

A
Scattering is the process of absorption of light energy only.

B
Scattering is the process of emission of light energy.

C
Scattering is the process of bending of light.

D
Scattering is the process of absorption and then re-emission of light energy.
