Waves

Mr. Anderson discusses the importance of waves, explaining their types, properties, and behaviors. He covers transverse and longitudinal waves, wave speed, frequency, and wavelength. The video includes a simulation of wave interactions and explores wave behaviors like reflection, refraction, and diffraction. Real-world examples, such as tsunamis, illustrate these concepts.

What is the primary function of waves in our daily lives?

• To generate light

• To produce heat

• To transfer energy and information

• To create sound

Which type of wave is created when you move a string up and down?

• Radio wave

• Transverse wave

• Electromagnetic wave

• Longitudinal wave

In a longitudinal wave, how do the oscillations occur?

• Perpendicular to the direction of motion

• In the direction of motion

• In a circular motion

• Randomly

What does the equation v = f * λ represent in wave theory?

• The relationship between speed, frequency, and wavelength

• The formula for calculating wave amplitude

• The equation for wave reflection

• The principle of wave interference

How is frequency measured in wave properties?

• In joules

• In Hertz

• In seconds

• In meters

What happens to a wave when it is reflected?

• It changes speed

• It bends

• It bounces back

• It disappears

What is diffraction in the context of wave behavior?

• Waves bending around obstacles

• Waves being absorbed

• Waves bouncing off a surface

• Waves speeding up

Which type of wave is more likely to bend around obstacles?

• Transverse waves

• Electromagnetic waves

• Low frequency waves

• High frequency waves

In the tsunami example, what is the frequency of the wave?

• 0.00067 Hertz

• 0.67 Hertz

• 310 Hertz

• 210,000 Hertz

Why is it important to understand wave dynamics in the context of tsunamis?

• To measure ocean depth

• To calculate the speed of sound

• To predict weather patterns

• To ensure safety and preparedness
