Required praticle graphs

Question 1

Stationary waves

What graph do you use and what is the gradient = to?

Answer 1

Y axis- 1/f
X axis- L
Gradient = 2 /speed of wave

Question 2

Youngs double slit
What graph do you use and what is the gradient = to?

Answer 2

Y axis- w
X axis- d
Gradient = Wavelength /s

Question 3

Cheak
Diffraction grating
What graph do you use and what is the gradient = to?

Answer 3

Y axis- d sin theta
X axis- n
Gradient = wave length

Question 4

Investigating emf

What graph do you use and what is the gradient = to?

Answer 4

Y axis- V
X axis- I
Gradient = -r
Y intercept = emf

Question 5

Determinning g
What graph do you use and what is the gradient = to?

Answer 5

Y axis- S (height)
X axis- t^2
Gradient = 1/2 g

Question 6

Resisity of a wire

What graph do you use and what is the gradient = to?

Answer 6

Y axis- R
X axis- L
Gradient = p/A

Question 7

Photoeletric effect

What graph do you use and what is the gradient = to?

Answer 7

x axis - hz
y axis - vs
Gradient = h/e

Question 8

How do you calculate the percentage uncertainty in the gratient?

Answer 8

(best fit gr - Worst fit gr)/Best fit gr X 100

Question 9

Graph to find the threshold frequency

Answer 9
