Answer 1

SPECTRUM = Spectrum is a a band of colours, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.

MULTIPLE REFLECTION =
Multiple reflection of light is thereflection of light back and forth several times between reflecting surfaces. If a reflected light ray isreflected again on being incident on another surface, it is termed multiple reflections. .

OPTIC NERVE = optic nerve is in each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.

Hope this helps you dude ☺️☺️✌️✌️✌️✌️

Answer 2

1.Spectrum

a band of colours, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength

2.Multiple reflection

Multiple reflection of light is the reflection of light back and forth several times between reflecting surfaces. If a reflected light ray is reflected again on being incident on another surface, it is termed multiple reflections

3.Optic nerve

The optic nerve is located in the back of the eye. It is also called the second cranial nerve or cranial nerve II. It is the second of several pairs of cranial nerves. The job of the optic nerve is to transfer visual information from the retina to the vision centers of the brain via electrical impulses.
