These lights are lights source or the source of light. other source of light can be incandescent light and the sun.

What you see in the picture is a plane mirror. Plane mirrors are mirrors with flat surface that produce images that are erect, have the same size, have the same distance, and virtual.

Mirror used in cosmetic purposes is a concave mirror to act as a magnifier of your face for better applying of the make up, lipstick and other cosmetic products. 

mirror used in the cars' side view mirror is a convex mirror. It gives a wider and clearer view outside.

As you can see, the pair of scissors is reflected in the mirror. since plane mirror is used, it has the same distance, same size and it is virtual.

                  The ball pen appears to be broken, due to refraction of light as it is dipped into the water

The human eye is a wonderful instrument, relying on refraction and lenses to form images. There are also many similarities between the human eye and a camera.

OPTICAL ILLUSION

when a curved mirror like this is struck by light and in front of an object, the image formed is real and projected unto a screen

sound is produced from vibrations mediums make. one example is the medium strings, when strings are struck, vibrations are created and travels in air then through our ears. that's why we hear music. irregular vibrations create noise

The wavelength of the blue light scatters better than the rest , predominates over the other colors in the light spectrum, and makes the sky appear blue to us.

water is a transparent medium which means light can travel through it. here we can see whats in the water

as light is incident upon an object, colors of the spectrum are either reflected and/or absorbed. this flower reflects the color pink and green and that's what our eyes see

When a beam of light shines onto something, that thing will cast a dark image of itself onto the ground or another surface. This image is  called shadow.
