Yes is the answer acceleration or velocity.

I am not sure, but I think the answer is between acceleration and velocity.

That is the diagram of the question. How is the reflected going to be?

oh okay, thank you.

Is that the final answer.

'^' means square which is I/Io= 0.25.

is it that the transmitted electric field is reduced by a factor cos (60) and the intensity is reduced by the square of that amount

I have solved in respect to angle 60. I made I/Io the subject of formula I=IoCos^2theta I/Io=cos(2*60...I/Io= -0.5

We are in a way saying the same thing; I need to find Io first then substitute in the formula above after finding I, the formula you said can now work.

I am looking for the fraction of the original intensity. I am back to square one of finding Io, which is needed to solve the question.

so i will do f=c/wavelength Then to find lamda2= c/f. So I am not using the angles given.

so, it will be I/Io=Cos60 which is I/Io=0.5

If the angle is 60, how will I calculate I when Io is unknown.

n1sintheta1=n2sintheta2 1*sin36=n2sin24 n2=sin36/sin24 n2= 1.45 to calculate wavelength is lambda=c/f My question is that that how do I find the wavelength without given the frequency.

I am not sure if theta will be 60 degrees or 30 degrees in this case and Io is given.
