**SAT 2 Physics Discussion Thread Oct 2015**

Some prep books its given the curve is ~12 miss -800 . The questions were confusing infact and invited the student to make careless errors

What was the second matching part, between the one with upward downward and the inclined plane?

@Shradheya410 The PR subject test book says a raw score >= 60 is an 800, but I know the actual is more along the lines of ~8 wrong = 800.

Not really 8. More like 10.

What was that easy amplitude question? I said four and may have not looked at if the mid level was 0 or 2… Is the answer 2 or 4 cm

@lsmhsh9798 4

Raw score =/= correct questions. 8 mistakes = -10 marks (rounded),

What was the answer for the question that gave n for both waves, and asked for the ratio of the velocity… I used n=c/v but forgot my answer… What did you guys get?

The one with the graph was just 5, no need for middle points.

I meant 4cm, sorry.

It was either 3/4 or 4/3. I can’t remember.

I said 3/4

^same

What can separate light? I said everything but a plane mirror

^same again

What was the one that asked what would the intensity of the bright fringes be if only one photon were emitted thru a slit at a time?

Same interference pattern. It didn’t specifically say intensity, it just asked what would happen? And what did you guys says to the elliptic orbital question? I said II and III.

What did you guys get for the 3 questions about the metal slit on the circuit. One asked what symbol it would be and the other two asked for graphs.

Which light bulb goes out? None of them right?

1.Ohm’s Law
2.The symbol for resistance(A)
3.Same graph as above but with half the slope. It was the only one that was linear.
