Tsunami caused by Sumatra earthquake

SLIDE 2

Waves: Definitions

Vibration (V) – Back and forth motion. Frequency (F) – The number of vibrations something makes in one second. Amplitude (A)– The size of the vibration. Resonance – Large vibrations when something is pushed at its natural frequency

SLIDE 3

What is your favorite type of wave?

A) Sound waves B) Water waves C) Light waves D) Earthquakes

SLIDE 4

Waves: Frequency

Frequency (F) – The number of vibrations something makes in one second.

SLIDE 10

Waves: Amplitude

Amplitude (A)– The size of the vibration.

SLIDE 11

What's the Frequency? F = ?

Waves: Frequency

Frequency (F) – The number of vibrations something makes in one second.

SLIDE 12

What's the Frequency?

Waves: Frequency

F = V / T = 4 / 2 = 2 Frequency (F) – The number of vibrations something makes in one second.

SLIDE 13

Waves: Frequency

F = V / T = 4 / 2 = 2 What's the Frequency? What's the Frequency? F = ? Frequency (F) – The number of vibrations something makes in one second.

SLIDE 14

Waves: Frequency

F = V / T = 4 / 2 = 2 What's the Frequency? What's the Frequency? F = V / T = 10 / 2 = 5 Frequency (F) – The number of vibrations something makes in one second.
