Wavelength and Frequency 6.2.5

​Recall that a wave is a pattern of motion that carries energy from one place to another. Light waves all have some properties in common:

• amplitude

• crest

• trough

• wavelength

Frequency describes how frequently, or how often, a wave passes a point.

Scientists measure frequency using hertz (Hz).

Things to remember:

• as wavelength increases, frequency decreases

• as wavelength decreases, frequency increases.

• high-amplitude waves carry high amounts of energy.

• low-amplitude waves carry low amounts of energy.

• high-amplitude waves are tall.

• low-amplitude waves are short

  
  
  

​What was the Cause of the Tsunami?

The 2004 Indian Ocean tsunami was a result of an under-the-sea earthquake that shook the floor of the seat resulting in a tsunami. The undersea earthquake was strong enough to set off a tsunami that spread across the Coast of Sumatra Island. Reportedly, the tsunami earthquake is recorded as the strongest in history as compared to Hiroshima atomic bomb.

Scientists claim that the shockwaves caused by the earthquake were equated to more than twenty thousand atomic bombs that devastated the city of Hiroshima. The quake recorded the highest figure in the history of earthquakes on the Richter scale. Therefore the tsunami was a result of the dangerous undersea earthquake.

​The Earthquake Recorded 9.1 Magnitude On The Richter Scale

The Tectonic Plates Collided Under The Sea Causing Enormous Shockwaves

The Tsunami Killed More Than 200,000 People And Destroyed Property 

The Environment Along The Beach Became Uglier After The Tsunami

The Early Signs and Warnings Before the Tsunami That Should Have Been Take Into Account: Unfortunately, children and some adults saw the disappearing of the ocean as an opportunity to go and collect stranded fish. They walked as deep as 3 kilometers deep into the sea before they got stranded and succumbed when the tsunami hit.
