Reflection of a Wave: Amplitude, Frequency, Velocity

Click For Summary

Homework Help Overview

The discussion revolves around the reflection of waves, specifically addressing the properties of amplitude, frequency, and velocity when a wave reflects off a mirror. Participants are exploring the implications of these properties in the context of wave behavior.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants express uncertainty about whether frequency changes upon reflection, with some suggesting that all properties might change. Others raise questions about the constancy of the speed of light in different media and its relationship with frequency and wavelength.

Discussion Status

The discussion is active, with participants providing tips and insights regarding the properties of light and waves. There are differing views on the constancy of the speed of light and its dependence on the medium, indicating a productive exploration of the topic.

Contextual Notes

Some participants are questioning the assumptions regarding the behavior of light in different media and the definitions of terms like frequency and velocity, which may not be fully clarified in the original problem statement.

Homework Statement



1. When a wave is reflected from a mirror, there is no change in its
a) Amplitude b) Frequency c) Velocity d) All

Homework Equations


The Attempt at a Solution



I think frequency changes,not sure
 
Physics news on Phys.org
i guess all
 
tip 1: If the frequency changes, the color of the light changes.
tip 2: the speed of light, c, is constant under all circumstances.
tip 3: \lambda = \frac{c}{f}

c is not constant in all circumstances.
it remains same in same medium
and it is c only in vacuum not in air

The speed of light depends of the medium. The ratio c/v is called the refractive index. The wavelength is v/f.
