Answer:
Light of a shorter wavelength should be used.
Explanation:
This is studied in the phenomenon called photoelectric effect, in which light is able to release electrons from a metal, said electrons are called photoelectrons .
The experiments that have been carried out show that <u>increasing or decreasing the intensity of the light will not cause the photoelectrons to be emitted</u>, what will cause the photoelectrons to be emitted is to increase the frequency of the incident light.
And a higher frequency corresponds to a shorter wavelength according to the equation:
(where is frequency,
the speed of light, and
the wavelength)
So the answer is that the wavelength of the light must be shortened to cause the emission of electrones.
Answer:
Q = 116.8 J
Explanation:
Here given that the temperature of 1 L hydrogen is increased by 90 degree C at constant pressure condition.
So here we will have
here we know that
n = number of moles
for ideal diatomic gas molar specific heat capacity at constant pressure is given as
now we have
