IGCSE PHYSICS DOUBTS HERE !!!!
SauD~:
Hmm, no one was posting in these thread, so i thought of coming up with doubts :P
When sounds refracts:
Speed: Decreases Wavelength: Decreases Frequency: Remains Same
When sounds reflects:
Speed: Remain Same Wavelength: Remain Same Frequency: Remains Same
When sounds diffract:
Speed: Remain Same Wavelength: Remain Same Frequency: Increases/Decrease
Please correct me if i am wrong :)
Thanks :D

the red part is wrong , the frequency in diffraction does NOT change

but in diffraction, i think something have to be changed :P
am i correct ^ ::)

If speed and wavelength remains constant then why should frequency change ? It cant and doesnt change in diffraction.
Diffraction is simply the spreading of waves as it passes through/around an obstacle.
