Two sinusoidal plane electromagnetic waves are identical except that wave Ahas a peak electric field that is three times the peak electric field of wave B. How do their intensities compare? (a) (b) (c) (d) (e) You cannot determine how their intensities compare from the data given.

Chapter 10 – Rotation of a Rigid Object About a Fixed Axis 10.1 – Angular Position, Velocity, and Acceleration kinematics are similar to translational motion - instead of x or y for position, we use θ for angular position s=rθ arc length s is related to angular position: π *The unit used for θ is the radian: θ rad)= θ (deg) 180° θf−θ i ∆θ - average angular speed: ω avg t −t = ∆t f i ∆θ dθ - instantaneous angu
