Yes, light exposure can be controlled by manipulating factors such as intensity, duration, and wavelength. This is commonly done in scientific experiments to study the effects of light on biological systems by ensuring consistent and controlled conditions.
In an experiment, light can be a controlled variable if researchers carefully regulate and maintain the level of light exposure to ensure consistency. This allows them to isolate the effects of other variables being tested in the experiment.
In observational studies, the independent variable (or exposure) is the variable that cannot be controlled by the researcher. This variable is already present and its impact is observed without any intervention or manipulation by the researcher.
The independent variable is intentionally controlled by the experimenter. This variable is manipulated to determine its effect on the dependent variable.
The independent variable is the component you change, such as the voltage or resistor value. The dependent variable is the component that changes in response to the independent variable, like the current or brightness of a light. The controlled variables are factors you keep constant, such as the type of wires or battery used.
In an experiment, the variable that cannot be controlled is known as the independent variable. This is the factor that is manipulated or changed by the researcher to observe its effect on the dependent variable. Controlling other variables helps to ensure that any changes in the dependent variable are due to the manipulation of the independent variable.

The exposure is controlled by the camera's light meter
The controlled variable for making glowing water could be the concentration of the glowing compound (such as a fluorescent dye or chemical) added to the water. By keeping the concentration consistent, you can ensure that any differences in glow intensity are due to the manipulated variable (such as the amount of light exposure or type of light source used) and not the concentration of the glowing compound itself.
Constant/controlled variables are variables that remain the same throughout an experiment. For example, if you wanted to see whether light affected how well plants grow, you would feed them equal amounts of water, so that the only variable affecting their growth was light exposure.
The controlled variable for a light bulb and battery experiment would be the type of light bulb or battery used. Keeping these variables constant ensures that any changes in the experiment are due to the independent variable being tested.
controlled variable is something that is controlled by the independent variable
Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.
A variable ND filter works by using two polarizing filters that can be rotated to adjust the amount of light entering the camera lens. By rotating the filters, the amount of light passing through can be controlled, allowing for adjustments in exposure without changing the aperture or shutter speed settings.
The variable that depends on the controlled variable is typically the dependent variable. This variable is measured or observed to see how it responds to changes in the controlled variable during an experiment or study.
The soil would be a controlled variable. The amount of light is the independent variable. Plant weight is the dependent variable.
