square
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.
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.
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.
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.
Intensity of a wave is proportional to the square of its amlitude so it should decrese when the amplitude is decreased.
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.

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.
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.
It is cosine*cosine*cosine.

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.
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.
It directly increases along with the growth in intensity of the light
