### Text of Ray diagram in concave mirrors

Slide 1

Ray diagram construction for concave mirrorsPresented byObina Johnson OkenyObjectives:To show how rays travel in order to form images in a concave mirrors.To show and state the nature of images formed.The paths of three rays are known.Rays traveling parallel to the principal axisRays passing through the principal focus Rays passing through the centre of curvatureCFP(a)Rays parallel to the principal axis are reflected and they pass through the principal focus

(b)Rays passing through the principal focus (F) will move parallel to the principal axis after reflectionCFP(c)Ray passing through the centre of curvature (C) are reflected back along their own paths because they are normal to the mirrorCFPFCPI am parallel to the principal axis. Always draw me firstI am the ObjectI am reflected and pass through F.For me, I pass through F firstI am reflected parallel to the principal axisI pass through C and I am reflected back along my own pathNow let us draw a ray diagram for an object beyond CFCPI am parallel to the principal axis. Always draw me firstI am the ObjectI am reflected and pass through F.For me, I pass through F firstI am reflected parallel to the principal axisNow let us draw a ray diagram for an object at CI am the image. What is my nature?FCPI am parallel to the principal axis.I am the ObjectI am reflected and pass through F.For me, I pass through F firstI am reflected parallel to the principal axisNow the object is between C and FI am the image now. What is my nature?FCPI am the ObjectI pass through C and I am reflected back along my own pathNow let us draw a ray diagram for an object at FWe will meet at infinity to form a real, inverted magnified image.FCPI am the ObjectI am reflected and pass through F.For me, I pass through F firstI am reflected parallel to the principal axisI pass through C and I am reflected back along my own pathNow let us draw a ray diagram for an object between F and PI am the image. What is my nature now?THANK YOU!You have been [email protected]
