What happens when you shine a flashlight at a wall?
Your body does not allow light to pass through it, so it will create a shadow on the wall. You can use all kinds of objects to block the light and make shadows. The closer the object moves to the flashlight, the bigger and fuzzier its shadow will be.
Why do police officers hold their vests?
The vest hang: A natural transition from the pit tuck, the vest hang is clasping the top of the vest near their collarbones to keep arms from hitting the equipment on the duty belt.

Is moon a light source?
The Moon can only be seen as a result of the Sun’s light reflecting off it. It does not produce any light of its own.
Does the human eye absorb light?
Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
What happens when you shine a light in your eye?
In bright light, it contracts. … More light creates more impulses, causing the muscles to close the pupil. Part of the optic nerve from one eye crosses over and couples to the muscles that control the pupil size of the other eye. That’s why the pupil of one eye can change when you shine the light into your other eye.
Why does the moon not spin?
In fact, the bright part of the Moon is experiencing daytime. The Moon does not rotate. The Moon does spin on its axis, completing a rotation once every 27.3 days; the confusion is caused because it also takes the same period to orbit the Earth, so that it keeps the same side facing us.
Why does the moon light up at night?
The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
Why is moon light white?
It’s a true physical effect, caused by the fact that – when the moon is low in the sky – you’re seeing it through a greater thickness of Earth’s atmosphere than when it’s overhead. The atmosphere filters out the bluer wavelengths of white moonlight (which is really reflected sunlight).
