A scientist from 1801 observes that shadows do not bend around corners and spread out.

Instead, they end sharply. Which theory of light is he most likely to support?

A) The wave theory, because bending around a barrier is a characteristic of waves
B) The wave theory, because anything that makes a shadow has to be made up of waves.
C) The particle theory, because Newton was the only known expert on the subject of light.
D) The particle theory, because only particles that travel in a straight line would cast sharp shadows.

You have NO IDEA how I dislike "homework" on this forum. Make a note of it.

But, I will help you nail the question by going to:

Professor Young's experiment. "A scientist", indeed.

He really supports NEITHER theory of light any more than the other.


EITHER model for light would explain this. Did he ever bother checking what the WAVELENGTH of the light is?


Plus, did he really need to be a scientist to figure that out? Everyone who has ever seen their own shadow knows that.

I think bending is the answer. At least it helped the space travelers.

D) The particle theory, because only particles that travel in a straight line would cast sharp shadows.

No, really! That 1801 scientist was pretty observant!
