Why does chlorophyll appear green in reflected light and red in transmitted light?

Why does star appears red in colour?

Why does an excessively thin film appear black in reflected light?

What is total internal reflection of light ? What are essential conditions of it ? Explain the formation of mirage using this phenomena.

Why does light appear to travel in straight line inspite of its wave nature.

Why does ZnO appear golden yellow at high temperature? Explain.

In the figure given below , the black line(upper) indicates action spectrum for photosynthesis and the lighter line (lower) indicates the absorption spectrum of chlorophyll 'a' , answer the followings: Wavelength of light nanometera(nm) If chlorophll 'a' is reponsible for light reaction of photosynthesis, why do the action spectrum and absorption spectrum not overlap?

If white light is used in the Newton's ring s experiment ,the color observed in the reflected light is complementary to that observed in the transmitted light through the same point. This is due to
