Can someone draw the diagram of Q4 (a) in this paper?

Thanks.

abcde is correct

draw a line perpendicular to the wavefronts. draw a normal to that line against th barrier than reflect that line followng reflection laws. now draw some wave fronts perpendcuilar to that reflected line keeping in mind that they should be the extension of waves hitting the barrier?
did u get anything? sorry i couldn't draw the digram. iam too lazy for that.
abcde u got that wrong i guess maybe frawing an arrow would have worked better

OMG! I'm so very sorry. I think this would be correct! :sorry: :sorry:

Thank you mrrul3z!

Lolx abcde u just drew normal to those wave fronts

I accept my mistake! This is the correct one. JazakAllah!

i realized the mistake too ...... THANKS FOR CORRECTING ME TOO

more explanatory

cant understand from the diagram bro

its easy draw the normal at a 90* angle and draw the emergent ray sin r equal to sin i as sin i/sin r = constant. so basically your ray diagram will look like that in the pic
