Waves Flashcards
1
Q
Phase difference
A
= 2πd ÷ lambda
d is the slit width
2
Q
Intensity (I)
A
= P÷ A
Energy transferred per second over an area of 1m²
3
Q
u ( total mass of the string divided by its total length)kgm-¹
A
= m÷L
4
Q
Energy of a wave
A
Is directly proportional to (amplitude)²
5
Q
Relative refractive index
A
= n1 ÷ n2
Where n2 is less dense
