Answer to Problem 65A
When the monochromatic light shining on the cesium metal is just slightly above the threshold frequency, the electrons are released with a low velocity.
Explanation of Solution
The
Monochromatic light means the light of one frequency.
When the monochromatic light is just above the threshold frequency, the electrons will be emitted. The electron will be having low velocity.
Interpretation: The intensity of the light increases, but the frequency remains the same is to be explained.
Concept Introduction: Single-wavelength light sources are known as monochromatic lights, where mono stands for only one chroma for color. The threshold frequency is a minimum frequency below which, regardless of the strength of the incident radiation, photoelectric emission is not possible.
Answer to Problem 65A
A greater number of electrons are emitted at a low velocity when the intensity of the light is increased.
Explanation of Solution
The photoelectric effect takes place when the frequency of light is higher than the threshold frequency.
Since the intensity is increased, there is the emission of more electrons but at a low velocity.
Interpretation: Monochromatic light of a shorter wavelength is used is to be explained.
Concept Introduction: Single-wavelength light sources are known as monochromatic lights, where mono stands for only one chroma for color. The threshold frequency is a minimum frequency below which, regardless of the strength of the incident radiation, photoelectric emission is not possible.
Answer to Problem 65A
There is an emission of electrons at a faster velocity due to the usage of a shorter wavelength.
Explanation of Solution
The photoelectric effect takes place when the frequency of light is higher than the threshold frequency.
Monochromatic light means the light of one frequency.
The wavelength and frequency are inversely proportional to each other.
Since the shorter wavelength is used, that means the higher frequency, so the emission of electrons occurs with a high velocity.

HOOC H₂NIC H 川 CH3 CH,CH3 Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the C-2-C-3 bond. 1. Edit the Newman projection on the canvas. 2. Replace the appropriate hydrogens with the appropriate -CH3 or other groups. 3. If you need to start over, Undo or choose a Newman projection from the Templates toolbar (bottom). Important: Never delete the hydrogen atoms or bonds directly attached to the template, and do not move them by dragging or dropping them. That will break the projections structures. Only replace them! ▸ View Available Hint(s) 0 2 H± 3D EXP. L ד י CONT. 2 H 0 N оarrow_forward
