Wave Motion Concepts and Applications

Mr. Salent, with his daughter Shenna and Denali, introduces a video tutorial aimed at providing solutions to homework problems related to wave motion and harmonic motion. The video covers the achievement scale for the waves unit, explaining what students are responsible for. It delves into the differences between wave motion and harmonic motion, using examples like radio waves, sound, and earthquakes. The tutorial also explains pendulum motion, cycles, and amplitude. It includes problem-solving using key equations and concludes with graph analysis of wave cycles.

Which topic is NOT covered in the waves unit this year?

• Destructive interference

• Wave interference diagramming

• Ocean waves

• Electromagnetic spectrum ordering

What type of motion is a car traveling at a constant speed on a highway?

• Wave motion

• Harmonic motion

• Linear motion

• Circular motion

Which of the following is an example of wave motion?

• A pendulum swinging

• A car accelerating

• A bulldozer moving

• Radio waves

What is the amplitude of a pendulum?

• The distance from the highest point to the equilibrium position

• The distance between two crests

• The number of cycles per second

• The time taken for one complete cycle

How is the period of a wave related to its frequency?

• Period is the square of frequency

• Period is the inverse of frequency

• Period is twice the frequency

• Period is half the frequency

What is the formula for calculating wave speed?

• Speed = Frequency * Wavelength

• Speed = Wavelength / Frequency

• Speed = Wavelength * Period

• Speed = Frequency / Wavelength

If a wave has a frequency of 25 Hz, how many waves pass a point in 3 seconds?

• 25 waves

• 50 waves

• 75 waves

What is the unit of frequency?

• Newtons

• Hertz

• Seconds

• Meters

What is the frequency of a wave with a period of 2 seconds?

• 4 Hz

• 1 Hz

• 0.5 Hz

• 2 Hz

Why can't the wavelength be determined from the given graph?

• The graph is incomplete

• The x-axis is in seconds

• The graph does not show amplitude

• The y-axis is in meters
