Types of waves
What are the different types of mechanical waves?
transverse waves, longitudinal waves, and surface waves
What is a pendulum?
A pendulum is when a weight is put on a fixed height with a rope, and able to be pulled back and forth, and freely move on it's trajectory.
What is the formula to find the frequency?
Frequency = 1/T (Period)
What is a tsunami?
A massive wave with a very long wavelength, caused by underwater disruptions like, landslides, earthquakes.
What is equilibrium?
When opposing forces are naturally balanced for a time.
What is a surface wave? Explain the definition.
A seismic wave that travels along the earth's surface
What was the use of pendulums before the invention of clocks?
in the 18th and 19th centuries, pendulums were used to control time, schedule daily life activities, work shifts, as well as public transportation.
What is the formula to find the speed or the movement of something?
Speed = Distance x Time = DT
What causes a tsunami to create massive waves on the shorelines?
Tsunamis occur because there is a sudden displacement of land underwater, which triggers, a powerful force to push water opposing from its source.
What is the definition of a wave crest?
What is an example of a standing wave we see in daily life?
Piano Strings or a jump rope
What is the synonym of the fixed point in a Pendulum?
An Equilibrium
What is the formula to find out the wavelength?
λ = v/f
λ = wavelength
v = velocity
f = frequency
What objects or actions can we do to reduce the height and slow down the wave on its impact on the land?
Growing more trees near shorelines can reduce the impact, like mangroves. Or creating smaller barriers to prevent bigger destruction.
What is propagation?
Propagation is the movement of waves
Define a body wave.
Body waves are low amplitude signals that, at teleseismic distances, propagate along a variety of paths through the mantle and core.
What are the factors contributing to stopping the bob in a pendulum?
Outside forces = gravity and friction
What is the formula, to find the time it takes to traverse something?
Distance / Speed = Time
What are the types of tsunamis? Name 3.
Local tsunami and Far Field or distant tsunami.
What is the definition of oscillation?
Oscillation is to measure its equilibrium value in time.
Tell me a real-life example of the Electromagnetic.
Radio waves transmission
What is the formula to find the period of a Pendulum?
Period = T
T = 2 pi L/G Squared
L = Length
G = Gravity
If the distance from point a to point b is 200 kilometers, and the train travels at around 100 kilometers per hour, then how long will it take to go to point b from point a?
200 km
100 km/h
v = distance/time
= 2 Hours
What type of wave is a tsunami?
A transverse wave
Define resonance.
Resonance is a phenomenon where an external force system forces another system around it to vibrate with a bigger amplitude at a specified frequency of operation.
