How is intensity of light related to photons?
Increasing the intensity of light will increase the number of photons arriving per second. Increasing intensity has no effect on photon energy.
At what light intensity do you expect there to be no net productivity?
100% light intensity ?
What is the effect of frequency of incident light on photoelectric current?
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.
What is a light intensity knob?
The light intensity knob is found on light microscopes and allows you to change the intensity of the light on the sample. Different light intensities allow you to view different parts more clearly.
Does water temperature effect evaporation?
no it does not
How is intensity of light related to photons?

How does changing the light intensity effect photosynthesis and why?
By changing the light intensity the rate of photosynthesis will either increase or decrease because it is one of the factors that affects photosynthesis. If you increase the light intensity the rate increases but if you decrease the light intensity the rate decreases.
What does the slope of the graph of photoelectric current versus intensity signify in the photoelectric effect?
The current rises as does the intensity of light detected. The more light the greater the intensity, and the greater the current. The answer to the question is that photoelectric current displayed on a graph is shown as a slope that varies with the intensity of light. Someimes it can go up, sometimes it can go down.The ultimate answer is that the photoelectric effect is unreliable, but it is improving!
Does color have effect on evaporation?
Dark colors absorb more light and therefore build up more heat, speeding evaporation.
Does color have effect on evaporation rate?
Dark colors absorb more light and therefore build up more heat, speeding evaporation.
What factor effects the intensity of light the color of light and the type of electromagnetic radiation that is given off by the electron?
Photoelectric effect
What are the two ways in which the sunlight increases the rate of transpiration?
generally speaking, transpiration speeds up when light intensity increases because the stomata respond to changes in light intensity. the other reason is that that sunlight may also warm up the leaves and increase evaporation.
What is the light intensity in the arctic?
The light intensity is poop!
What Is The Negative Effect Of Evaporation?
A negative effect of evaporation is that the liquid turns into gas.
What is the effect of temperature on the effect of evaporation?
Rapid evaporation helps reduce the temperature of water.
What environmental factors directly influence photosynthesis?
well, temperate, light intensity, and weather effect the rate of photosynthesis
Refer to your graph of productivity and light intensity At what light intensity do you expect there to be?
0% light and 25% light
