4-30. The threshold frequency of a metal can be
determined from measurements of the speed of
the ejected electrons. Electrons were ejected from a
metal with a speed of 5.00 × 105 m-s¹ when irradiated
by light having a wavelength of 390.0 nm. Determine
the threshold frequency of this metal.
In a fluorescence experiment, the measured emission intensity will increase with
higher power of incident light.
True
O False
Do the results from Study 1 support the claim that photovoltaic cells capturing
different frequencies function at varying efficiencies with changes in
temperature?
A
Yes, because as temperature increases, efficiency decreases.
No, because all photovoltaic cells function
regardless of frequency.
the same efficiency
No, because there is no uniform change in efficiency as related to
temperature.
C
Yes, because as temperature increases, so does efficiency.
