Homework Answers
4. We see world due to reflection. Light coming from objects after reflection is perceived by our eyes. We see only that colour which is reflected by the light and all other colours are absorbed. So,
A yellow shirt absorbs blue light and reflects yellow light.
5. Waves mixes up. Interference, diffraction are intuitive properties of waves. So,
Young's double slit experiment shows that light sometimes behave like a wave.

1. It is hard to get the bars to be parallel in this experiment. Explain why the bars tend to be so wiggly That happens because there is not match friction between the glass plates and it makes it hard to move them gradually relatively to each other, plus the surfaces of the glass plates are not entirely even which makes the friction vary in different areas of the glass plates and their movement...
