Why does the intensity of light decrease as the distance from the source increases?
The intensity of light decreases with distance due to the spreading out of light waves over a larger area. This phenomena is a result of the inverse square law, which states that the intensity of light is inversely proportional to the square of the distance from the source. As light spreads out, it becomes less concentrated, resulting in a decrease in intensity.
How does amplitude affect light intensity?
Amplitude of light waves directly affects the intensity of light. As the amplitude increases, more energy is carried by the light wave, resulting in higher intensity. Conversely, a decrease in amplitude leads to lower light intensity.
Intensity of light depends on the?
The intensity of light depends on the amplitude of the light waves, which represents the strength or power of the light wave. The intensity is also affected by the distance the light has traveled from the source, which can cause the light to spread out and decrease in intensity. Additionally, materials through which light passes can affect its intensity through absorption or scattering.
What is the increase and decreases the light intensity on a microscope?
To increase light intensity on a microscope, you can adjust the condenser aperture or use a brighter light source. To decrease light intensity, you can close the condenser iris diaphragm or dim the light source. Balancing light intensity is crucial for optimal viewing and imaging.
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.

Could photosynthesis decrease if you increase light-intensity?
Temperature affects the rate. Because of it is using enzymes.

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.
How do you correct the light intensity from low to high on your microscope?
To correct the light intensity on a microscope, you can use the light intensity control knob or dial located on the microscope power supply. Adjust the knob or dial clockwise to increase the light intensity and counter-clockwise to decrease it. Gradually increase the light intensity until you achieve optimal brightness for your sample without causing glare or overexposure.
What would occur if light intensity reduce slightly to a plant?
The rate at which oxygen is released from the plant will decrease.
How do you use a light intensity meter?
To use a light intensity meter, first turn it on and hold it in the area you want to measure. Make sure it is facing the light source directly. Take a reading of the light intensity and note the value displayed on the meter.
How does light intensity vary with distance form the source?
Light intensity decreases as distance from the source increases. This is because light spreads out in all directions as it travels, causing the same amount of light to be distributed over a larger area the further it travels. This decrease in light intensity follows an inverse square law, meaning that the intensity decreases proportionally to the square of the distance from the source.
Why does the intensity of light change with distance?
The intensity of light decreases with distance due to the spreading out of light waves over a larger area as they travel farther from the source. This spreading out of energy leads to a decrease in the concentration of light at any given point, resulting in lower intensity.
