How long does it take for a short pulse of light to travel from one end of the glass to the other?
Express your answer in terms of some or all of the variables f and L. Use the numeric value given for n in the introduction.
T = ___________ s
Answer:

Step-by-step explanation:
Given:
Thickness og glass = L
Index of refraction n=1.5
Frequency = f

λ(air) 
λ(glass) = λ(air) / n
= 
= 
= 
V(glass) = fλ(glass)


Answer:
c. 
Step-by-step explanation:
Since the divisor is in the form of
, use what is called Synthetic Division. Remember, in this formula, <em>-c</em> gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
4| 3 −11 −4
↓ 12 4
_______________
3 1 0 → 3x + 1
You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [3x² - 11x - 4]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 3 in your quotient can be a 3x, and the 1 follows right behind it, giving you the quotient of
.
I am joyous to assist you anytime.
The answer would be C) 2x + 10.
Expand ( -3x + 5x + 10 )
Simplify ( 2x + 10 ).
Hello again lol. I would think it would be two rooms don’t count me on this one but I think it is two
