12B.5.1 Waves Intro

Displacement: (x/m) is the distance of a waves oscillation from its point of _______________

Wave speed: (v/ms⁻¹) is the distance ___________ by the wave per unit time

List the features of two particles that are in antiphase

• Oscillating in time with each other

• Oscillating out of step with each other

• One reaches its maximum positive displacement as the other reaches its negative

• Have the same frequency

• Reach maximum positive displacement at the same time

Wavelength: (l/m) is the distance between two identical points of same _________

What is the phase difference between the two waves

• 0°

• 90°

• 180°

Frequency: (f/Hz or s⁻¹) is the number of ____________ per unit time

_______________: point of highest density

Convert 5/9𝜋 rad into degrees

(just write the number, don't include degrees etc.)

Amplitude: (A/m) is the maximum ______________ from the point of equilibrium

What is the phase difference between the two waves

• 0°

• 90°

• 180°
