but i screwed up 2 question which i was so pissed off
i knew the ans..but i over rules my insticnt!!!
the longitudnal one...
i said 14n2
but i KNEW the ans was 2n4
bte the pressure for pistion
both ould dec right
Pressure 100% dec what about density
Few of my friends also thought 1, i was sure that it was 2 and 4 though.
Yup, pressure and density both decrease. It is mainly due to the increase in volume.
it is 2 n 4
cuz waves in water r transversal
n thee shallow to deep was D right?
The shallow one, I got C. Because when it goes into the shallow area, it moves slower, thus wavelength decreases, and since it has entered the area at an angle, it will refract (towards the normal in this case). D, although showed a decrease in wavelength, but the there was no refraction..so i think C is wrong..Sorry about that
Well, good luck for chemistry, if you take chemistry
