If the amplitude of a wave changes which also changes?
If the amplitude of a wave changes, the intensity of the wave also changes. The intensity of a wave is directly proportional to the square of its amplitude. So, as the amplitude increases, the intensity increases as well.
What is the Lambert Cosine Law and how does it relate to the reflection of light?
The Lambert Cosine Law states that the intensity of light reflected off a surface is directly proportional to the cosine of the angle between the incoming light and the surface normal. This law helps to explain how the brightness of a surface changes based on the angle of incidence of light.
How does distance affect intensity?
Distance affects intensity by following the inverse square law, which states that as distance from a source increases, the intensity of the source decreases by the square of the distance. This means that the further you are from a source of intensity, the weaker the intensity will be.
How does intensity work?
In general, intensity refers to the amount of energy or power carried by a wave. In the context of sound and light, intensity is proportional to the square of the amplitude of the wave, meaning that doubling the amplitude increases the intensity by a factor of four. Intensity is measured in watts per square meter.
Does the intensity of a wave increases when its amplitude decrease?
Intensity of a wave is proportional to the square of its amlitude so it should decrese when the amplitude is decreased.
What is Malus' law?
The Malus' law states that the intensity of the polarized light transmitted through the analyser varies as the square of the cosine of the angle between the plane of transmission of the analyser and the plane of the polarizer. Mathematically, it would be: I ∞ cos2θ or I = I0 x cos2θ.

What the cosine of 45 degrees?
cosine 45° = √2/2 (Square root of 2 over 2)
What physical law describes the manner in which the intensity of sunlight changes as the observer moves away from the sun?
The physical law that describes how the intensity of sunlight changes as the observer moves away from the sun is known as the inverse square law. This law states that the intensity of sunlight decreases in proportion to the square of the distance from the sun. This means that the farther away an observer is from the sun, the weaker the intensity of sunlight they will experience.
How does distance affect intensity?
Distance affects intensity by following the inverse square law, which states that as distance from a source increases, the intensity of the source decreases by the square of the distance. This means that the further you are from a source of intensity, the weaker the intensity will be.
What is cosine cubed?
It is cosine*cosine*cosine.

What is the cosine of angle b?
I could answer that for you in a snap if I knew the size of angle 'b'.Without that information, no answer is possible.Wait! There is an answer. Not a useful one, but an answer nonetheless.The cosine of angle 'b' is the square root of [ 1 minus the square of the sine of angle 'b' ] .You heard it here first.
The inverse of the cosine function?
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.
How does the rate of photosynthesis respond to changes in light intensity?
It directly increases along with the growth in intensity of the light
