2. Over two thousand years ago, the Chinese were already using
a pin-hole to create images. State the principle for the use of
pin-hole camera and the formation of pin-hole image.
Based on the fact that light travels in the
straight line.
Based on Reflection of Light
Based on Refraction of Light
Based on Diffraction of Light
3. We cannot see light in outer space. Why?
There is no air in space, so light cannot travel
through space.
There are only very small amount of dust
particles in outer space, we cannot see light as it
travels through space.
Black hole in space to attract all the light in space.
The sun's rays are not strong enough to
illuminate the space.
