When red light is compared with violet light, a. both have the same frequency. c. both travel at the same speed. b. both have the same wavelength. d. red light travels faster than violet light.

The correct answer to your question would be C. Both travel at the same speed.

Ex. When red light is compared with violet light both travel at the same speed.

Hope this helped, great day :)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
