10.7 Newton's Second Law for Rotation

Newton's second law for rotation, ∑iτ i = I α ∑ i τ i = I α, says that the sum of the torques on a rotating system about a fixed axis equals the product of the moment of inertia and the angular acceleration. This is the rotational analog to Newton's second law of linear motion.

Introduction to Polarized Light

The principle behind Brewster's angle is illustrated Figure 3 for a single ray of light reflecting from the flat surface of a transparent medium having a higher refractive index than air. The incident ray is drawn with only two electric vector vibration planes, but is intended to represent light having vibrations in all planes perpendicular to the direction of propagation.

Snell's Law -- The Law of Refraction

Snell's Law. Like with reflection, refraction also involves the angles that the incident ray and the refracted ray make with the normal to the surface at the point of refraction. Unlike reflection, refraction also depends on the media through which the light rays are travelling. This dependence is made explicit in Snell's Law via refractive

Measuring Vibration

Measuring Vibration - Page 6. The Difference Between RMS, Peak and Peak to Peak Amplitudes. The "RMS" value is calculated by simply multiplying the peak amplitude (shown in the graphic below) by 0.707: RMS = Peak x 0.707. But is that technically correct ? Technically, the RMS value of a pure sinusoid is equal to the area under the half-wave.
