An atom's mass number equals the number of protons plus the number of neutrons.
Hope this helps! (:
The critical angle formula should be: sin^-1(1/n)
where "n" is 1.501 into the air
<span>The critical angle of light travelling from benzene, happens because the larger angles of incidence from the inside of the benzene has experienced the total internal reflection. </span>
Hello.
The answer is: D. wavelength
This is correct because frequency x wavelength = speed
Have a nice day
