Final answer:
Phase 1 stabilization refers to a reduction of intensity by 90%, leaving 10% of the original intensity. One uses the equation I = Io cos² to solve for the angle that produces this reduction. The equation highlights wave behavior in physics.
Step-by-step explanation:
When discussing Phase 1 stabilization and intensity, we are referring to when the intensity of a signal or light is reduced by 90%. This means that the remaining intensity is 10% of its original value. This can also be expressed as 0.100 times its original value. Using the provided equation I = I0 cos²(θ), where I is the final intensity and I0 is the original intensity, we can find the angle θ that corresponds to this level of intensity reduction.
For example, if we want to reduce the intensity to 10% of its original value, the equation becomes 0.100 I0 = I0 cos²(θ). By solving this equation, you can find the value of θ that gives a 90% reduction in intensity, leaving 10% of the originally measured intensity. Such calculations are often used in physics to understand wave behavior, including light and sound waves.
