If you assume linear relation between the brightness and number of photos (linear case; in some cases it's not true) than the number of photons will double too.

What is measured in units of lux?
Lux is a measurement of light, the brightness at source. The higher the number the brighter the sourceIllumination, the light output of a light bulb.
What are the 3 measurable quantities of light?
The 3 measurable quantities of light are:* Luminous intensity-- which refers to the brightness of a light source* Luminous flux-- is the rate at which light is emitted from a source and strikes the surface of a whole sphere* Illumination-- is the deliberate application of light to achieve some aesthetic or practical effect
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
What receptor is responsible for adjusting the light and brightness in your eye?
Photoreceptor
What is an electrically produced source of brightness that rhymes with kite?
light
How would you measure the brightness of light being produced by a source?
photometer or light meter
What does lumosity mean?
Lumosity refers to the level or quality of brightness emitted by something, such as a light source or a reflective surface. It is often used to describe the intensity or brilliance of light.
What is a lumen of light?
A lumen of light is a measurement of visible light. It means the brightness of light and can vary depending on the light source.
Do adding more batteries increasing the brightness of light?
Yes more batteries/power equals more brightness to a source
What is the brightness of a diamond?
A diamond 'gathers' light from every available source and reflects and refracts it back to the eye of the observer. Its brightness then, depends on how much available light the diamond can collect.
What is measured in units of lux?
Lux is a measurement of light, the brightness at source. The higher the number the brighter the sourceIllumination, the light output of a light bulb.
What is measured in units of luxs?
Lux is a measurement of light, the brightness at source. The higher the number the brighter the sourceIllumination, the light output of a light bulb.
Is the brightness of glow in the dark materials affected by the light source used to make them glow or only by the intensity of the light Does the light source?
It depends on the luminescence of the materials. I see no difference between "the light source" and "the intensity of the light". Please restate and/or clarify the question.
What is brightness as sound is to light?
Loudness is to brightness as sound is to light.
When a source of dim orange light shines on a photosensitive metal no photoelectrons are ejected from its surface What could be done to increase the likelihood of producing photoelectrons?
increase the brightness of of the orange light source
Why and how do shadows change?
Shadows are places where the light cant get to, so depending on where the source of light is, the power or brightness of it and the size of the object, the shadow will change.
