Light concepts

The ray of light that falls on the reflected surface is called ........

• Refracted ray

• Reflected ray

• Incident ray

• Normal

What is the angle of reflection (θ_r) in the image?

• 56^o

• 90^o

• 124^o

• 34^o

Why does the straw appear to be bent?

• light is reflected

• light is absorbed

• light is turned

• light is refracted

The illustration shows a light ray striking an object.
In the illustration, the light ray striking the object is-

• absorbed
• stopped
• reflected
• refracted

If the Light ray while travelling from one medium to another bends towards the normal, what can be the possible scenario?

• It went from water to air

• It went from glass to water

• It went from water to glass

• It is being reflected back

Which of the following colours gets reflected when white light falls on a green ball?

• Yellow

• Green

• Orange

• Indigo

Why is the spectrum of light seperated into its components of colour when white light is directed to a prism?

• The different colours in the white light bend away from the normal line at different angles when entering prism

• The different colours in the white light bend towards the normal line at different angles when entering prism

• The different colours in the white light bend away from the normal at same speed to each other when entering prism

• The different colours in the white light bend towards the normal at same speed to each other when entering prism

Which colour is seen at the top of a rainbow?

• Blue

• Green

• Red

• Yellow

When a beam of white light is passed through a prism it splits into it's component colors. This is called

• Converging Of Light

• Refraction Of Light

• Dispersion Of Light

• Reflection Of Light

The angle between the ray of light that is bent, and the normal is called.......

• Angle of incidence

• Angle of reflection

• Perpendicular

• Angle of refraction
