Equations and their Components (Waves) Flashcards
1
Q
n
A
Order of spectrum
2
Q
λ
A
Wavelength of wave (m)
3
Q
x
A
Distance between central fringe to the nth fringe (m)
4
Q
d
A
Distance between slits (m)
5
Q
f
A
Actual frequency (Hz)
6
Q
f’
A
Apparent frequency (Hz)
7
Q
Vw
A
Velocity of the wave (ms-1)
8
Q
Vs
A
Velocity of the source (ms-1)
9
Q
θ
A
Angle from central fringe to nth fringe (rad)
10
Q
L
A
Distance from diffraction grating to screen (m)
11
Q
N
A
Number of splits per metre in diffraction grating
12
Q
d
A
Slit spacing (m)
13
Q
Conversion from Nanometers to Meters
A
Divide by 1,000,000,000 (1 billion)
1 Nanometer (nm) = 1 × 10⁻⁹ meters (m)
E.g. 100 nm = 100 ÷ 1,000,000,000 = 1 × 10⁻⁷ meters
