What else can I help you with?
If cardboard were four times the unit distance away from the bulb how much would the light falling on the cardboard be?
The intensity of light falling on the cardboard would be 1/16th of the original intensity because the intensity of light is inversely proportional to the square of the distance from the source.
How would you measure the brightness of light being produced by a source?
The brightness of light produced by a source can be measured using a device called a photometer or lux meter. These tools measure the illuminance of light in lux, which is a unit of measurement for the amount of light that reaches a surface. By placing the photometer at the location where the light is being emitted, you can quantify the brightness level.
What colour would a white shirt look like underneath a green light disco light?
Under a green disco light, a white shirt would likely appear to have a greenish tint, as the light would reflect off the fabric. The brightness of the green light could also cause the shirt to look less vibrant, potentially making it appear more muted or washed out. Depending on the intensity of the light, shadows and textures on the shirt may also be accentuated, altering its overall appearance.
What does 6300 light years equal to in earth years?
A light year is a measure of distance not time. A light year is the distance light travels in one year. So for light to travel 6,300 light years, would take 6,300 years
What color would a green object look like with blue lights?
A green object illuminated by blue lights would likely appear to have a bluish hue. The blue light would mix with the green, potentially creating a teal or cyan effect, depending on the intensity of the blue light and the specific shade of green. This color blending occurs because the blue light affects how our eyes perceive the green object. Overall, the object may look less vibrant and more muted than it would under white light.
What would you use to measure light intensity?
A light meter is typically used to measure light intensity. These devices capture the amount of light in a particular area and provide a quantitative measurement in units such as lux or foot-candles.
What is the instrument for measuring light?
A photometer would measure the intensity of light, and a spectrometer would determine which frequencies are present.
What equipment would you need to test hypothesis the distribution of invertebrates in a habitat depends on light intensity?
Petri dish Black marker Lamp Invertabrate
What instrument would you use to measure the amount of light under a tree?
A light meter is commonly used to measure the amount of light under a tree. It measures the intensity of light in lux or foot-candles, giving a numerical value that indicates the level of illumination in that area.
Which color has the greater intensity?
Intensity is a measure of the brightness or saturation of a color. Typically, brighter or more vibrant colors such as red, orange, and yellow are considered to have greater intensity compared to darker or more muted colors like blue, green, or purple.
Where would be the intensity higher?
To determine where the intensity would be higher, one would need to consider the context, such as sound, light, or energy. For instance, in sound, intensity is higher closer to the source of the sound. In terms of light, intensity is greater near the light source and decreases with distance. Generally, intensity diminishes with increasing distance from the source in most physical phenomena.
What piece of apparatus would you use to measure abiotic factors?
You would use a data logger with sensors such as a thermometer, hygrometer, anemometer, pH meter, or a light sensor to measure abiotic factors such as temperature, humidity, wind speed, pH level, and light intensity in a given environment.
Are decibels used to measure light?
Absolutely. Photographic light meters are designed to measure light for photographic exposure (in a film-speed/shutter-speed/aperture combination), but many hand-held photo light meters can measure light in footcandles, which is a common scale. If you look on places like eBay, you can find inexpensive, digital, brand new meters which read out in Lux or Lumens. Some may read in footcandles as well. It's not difficult to convert from one measure to another (there should be internet calculators which would do it easily).
If cardboard were four times the unit distance away from the bulb how much would the light falling on the cardboard be?
The intensity of light falling on the cardboard would be 1/16th of the original intensity because the intensity of light is inversely proportional to the square of the distance from the source.
Refer to your graph of productivity and light intensity At what light intensity do you expect there to be?
The graph shows that productivity increases with increasing light intensity, reaching a peak before plateauing. Therefore, at the light intensity where productivity peaks, you would expect the highest productivity level before it starts to level off.
What is Formula for converting watts to foot candles?
Foot-candle is a unit of light intensity, not of power like watts. The power would vary, depending on the color of the light.Foot-candle is a unit of light intensity, not of power like watts.

Why would it be hard to find the light intensity if the temperature were very hot or cold?
because if the light changed them so would the temperature
