SUMMARY

The discussion centers on the method of drawing reflected wavefronts, specifically in relation to a provided image. Participants emphasize that reflected wavefronts are perpendicular to the reflected ray and suggest using a protractor, pencil, and ruler for accurate representation. The key technique involves drawing the mirror image of the original wavefront about a plane that is perpendicular to the reflecting surface. This approach ensures clarity in understanding the concept of reflection in wavefronts.

PREREQUISITES
  • Understanding of wavefronts and their properties
  • Familiarity with reflection principles in physics
  • Basic skills in geometric drawing using a protractor and ruler
  • Knowledge of how to interpret and create mirror images
NEXT STEPS
  • Research the principles of wavefronts in physics
  • Learn about the laws of reflection and their applications
  • Practice drawing geometric reflections using a protractor and ruler
  • Explore advanced topics in wave optics, such as interference and diffraction
USEFUL FOR

Students studying physics, educators teaching wave optics, and anyone interested in mastering the concepts of reflection and wavefront representation.

How would one draw reflected wavefronts? I do not get this concept. I have attached a question below, and I do not necessarily ask anyone to solve this but teach me on how to provided that I have a protractor, a pencil and a ruler.

Thanks

I wonder if I'm understanding your question correctly.
This is an easy Google image search for "reflected wavefronts".
Here is a result for reflection:

Here's refracted:

Can you draw the reflected ray? If so, the reflected wavefronts would be perpendicular to the reflected ray.
 
If I use that logic, it doesn't work here:

I don't think so you did. I meant on how to draw in relation to the image I have attached.

Draw the mirror image of the attached image about a plane perpendicular to the reflecting surface.
 
Then, how do you reflect this one?

The same way as shown in the top figure in post #2. What's your problem?
 
Please describe what you think those graphs are showing.
Tell us what you know about reflection and wave fronts.
Your questions appear to be profoundly elemental.

Time to close this thread as the OP has received some excellent answers and needs some time to ponder them.

Thank you all for contributing here.
