Topic: Wave Characteristics and Behavior 13 Assessment: Level 2c: Objectives: I can solve problems involving intensity, amplitude, and the inverse square law. I can solve problems involving Molus' Law. I can explain whether transverse or longitudinal can be polarized. I can explain why reflected waves do or do not change sides on reflections based on the boundary conditions. r__ n I __l a??? if:- if c0526} I h"- ml 1. A wave pulse on a string is reflected from a fixed end causing the pulse to return on the opposite side of the string, Explain why the reflected pulse was on the opposite side of the string. [2] 2. The intensity of light 2.0 meters away from a light bulb is 28 W.m-2. Calculate the intensity of the light 6.0 meters from the light bulb. ?C7 12]3. A sound wave has an amplitude of 520 Pa at point P and 320 Pa at point Q. Calculate the ratio of the energy carried by the wave a point P to that at point Q. [3]4. Calculate the ratio of the amplitudes of a wave at 2.0 meters from the source compared to 4.0 meters away from the source. [3]
