1what evidence did sir isaac newton use to support his particle explanation of
light?
a light produces an interference pattern.
b light causes electrons to be emitted from a metal surface.
c light reflects off metal surfaces,
d light travels in a straight line, and it casts a shadow.

Light travels in a straight line, and it casts a shadow.

Explanation:

This evidence allowed Sir Isaac Newton to elaborate his particle theory of light (also called corpuscular theory) which consider light as discrete particles travelling in straight line. Unfortunately, this theory cannot explain refraction, diffraction and interference, which require an understanding of the wave theory of light.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
