GCSE Physics - How Lenses Work #69 

I just wanted to come say that you're videos are short, sweet, to the point and explains everything really well according to the GCSE and CSEC syllabi and they have been a MAJOR help for my students and I since we have all went fully virtual with school. All my students (advanced or not) have found your videos super helpful and I want to thank you for the work you put into these videos. It's much appreciated by students in the Caribbean. I hope you see this comment and the others because u are one of the best channels on youtube in terms of assisting secondary school students in their subjects. Hope all is well with you during this pandemic despite everything. I wish you all the best. 🇹🇹#868

The video is fantastic, but the correct spelling is principal focus and not principle focus

COGNITO, thank you for your services of supplying us with good details on how the lenses function. You are truly a excellent teacher of optical technology. But here's a question I have: how does the lenses in a camera correct the inverted image(from a convex lens) into a upright position? Is it done by combining a convex lens with a concave lens because a concave lens give off an upright image, or is there something else at play?

THANK U SOO MUCH! THIS HELPED ME

Great video. Question: the chicken image on the screen at 4:28 appears to be behind the focal point. Is that correct?
