For instance how to explain refraction from a lighter medium to a denser medium using wave theory?Could you be more specific, please? Link an example if you can.

Me too! But Thanks anyways!I'm sorry I'm already a graduate and I'm pretty sure we didn't take that. I hope someone else answers.
Q. How much the momentum of a body would increase by increasing the K.E by 300%?...........the ans is 100%.....but could someone please explain to me the method to solve this question.....would appreciate it a lot!
Hey need help !
I want to give a 3rd A-level so i wanted to ask. I've done Biology & Chemistry and AS AICT.
shall i do Physics or math? Which is an easier subject that will allow me to prepare in 3 months?
Help answer ASAP!
Where did you get this question from??Answer this question yo people of the world!!!
Where did you get this question from??
The answer seems to be B
At time t=0
air resistance zero as the velocity is zero
remember air resistance is dependent on velocity.the greater the velocity the greater the air resistance.
anyway the body's velocity increases till T so air resistance should also increase.
Before T is reached the air resistance gradually increases at a decreasing rate.This is because the velocity is increasing at a decreasing rate.
after T the velocity becomes constant so air resistance also becomes constant
Assalamuailkum Everyone.....can someone tell me SI base units of Power(frm May/June 2013 22)....the answer I am getting is Nms^-1 ....is this correct?? Also.....There is a question about Radioactivity in an aplpha particle...(9702/22/M/J/13 Q 7 a ii).....Explain why the mass seems not to be conserved in the reaction...this question bugs me bcoz everywhere i read it said that...
Total energy (rest mass energy plus kinetic energy)
Number of nucleons
Momentum
Charge
are conserved....please help me out!!!
Hi! I need help pls!
The question is: "Why does the moon not fall and hit the earth?"
