That cleared everything for me, Thanks a lot !

Greetings , Is the zero potential level ( not the ground state) considered as an excited state ? and why the ground state isn't an excited state ?

it will end up with ##n_1 \sin{\theta_1} = n_2 ? , n1 is denser than n2 since its greater than I know the fact that critical angle occurs only from denser medium to less dense , and that's why I get confused when I find relative refractive index

Greetings, Do we use Absloute refractive index when finding crtical angle ? if it was two mediums ( not vacuum or air) how would i calculate the critical angle ? I mean i get confused when I find relative refractive index because sometimes i get sine inverse greater than 1 which give no...

Isnt it possible to solve it by the equation I have given ? it will be the same on both sides , but one will have the coefficient (3/4). At the same time , it say in equilibrium position , so one side will have x=0, and so max. velocity (K.E) but i am facing problem in which side to place them...

well , iam not used to PE = 1/2kx2 :(

Do you mean hooks law F=-kx ?

Homework Statement Can I get help in part (b) of this question ? Homework Equations KE=1/2 m v2 v= (2π f )√(A2 - x2) The Attempt at a Solution I substituted the second equation into first one, so i got KE= 1/2 m (2π f )2 (A2 - x2) but then couldn't complete

so in case of 6(x-2) , the translation is +12 , but in 6x-2 , translation is +1/3 ?

The problem is these types of questions comes in multiple choice so i won't have enough time sketching or plotting. I couldn't get the difference between e6(x-2) -4 and e6x-2 -4

how do i know if the stretch is carried first or the translation ? and what's the difference if it was the opposite

how +2 isn't correct ? ,,,its like f(x-2) which means translation of +2 in x direction ( to right )

Homework Statement Describe the transformation in : y=e6x-2 - 4 y=6ex-2 - 4 ? Homework Equations --- The Attempt at a Solution 1)So 6x means stretch parallel to x-axis at s.f of 1/6 and then translation of ( +2 , -4 ) 2) the same but the stretch is parallel to y-axis at s.f of 6 but...

Greetings , Many Doppler effect questions require to find the final Frequency/Wavelength. so after using the equation : Δλ / λ = v / c or Δf / f = v / c How can I know if the change in Frequency/Wavelength is positive or negative to calculate the final frequency or wavelength. because...

Thank you both
