Thank you for this 🙂 Reply SalfordAcoustic · January 17, 2019 at 11:37 am Glad you liked it. We’ll be adding more during the spring as we bring stuff across from another site. Reply Miss Kent · March 20, 2019 at 9:48 am When teaching Huygen’s principle, I used to use an excellent animation of yours, found at: http://www.acoustics.salford.ac.uk/feschools/waves/flash/huygens.swf I was really disappointed today to see that it was gone! Any chance you could send it to me, or put it back on your website? Thank you!!
