The following diagram shows a driver who could see the image of a vehicle behind him without turning his back. Why?

Light travels in a straight line

Light travels in two different mediums

When does the light is refracted?

When light travels in two different mediums

When light travels in a straight line

When light cannot pass through an opaque object

What is the conclusion from your observation in this picture?

Light travels in a straight line

Light can pass through a transparent material

What causes the formation of a rainbow?

Light travels in a straight line

Light in bounced in two different mediums

Why is the component of colour in a rainbow can be seen when light passes through a glass prism?

phenomena of dispersion of light

phenomena of scattering of light

phenomena of reflection of light

phenomena of diffraction of light

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 towards the normal line at different angles when entering 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 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

Why is red light is at the top whileviolet at the bottom of the spectrum?

Red light has the highest speed so it is refracted the least.

Violet light has the medium speed so it is refracted the least.

Violet light has the highest speed so it is refracted the least

Red light has the slowest speed so it is refracted the least

Look at the diagram given. This is the first prism. What happen if A SECOND inverted prism is placed behind the first prism?

the various colours pass through it and form a white light back

the various colours pass through it and form brighter spectrum

the various colours pass through it and form an opposite spectrum colours

This is the example of dispersion of light

sky looks bright orange in the evening

these are examples of phenomenon of scattering of light except

Sky appears reddish in the evening

Why does scattering of light occur?

Light rays are blocked and reflected to all directions by the clouds or particles in the air

Light rays are blocked and reflracted to all directions by the clouds or particles in the air

Light rays are passing through and refracted to all directions by the clouds or particles in the air

How does light behave when hitting this shirt?

Yellow is reflected; all other colors are absorbed.
