Wave Properties and Behavior

The video tutorial explores the speed of waves, emphasizing its dependence on the medium due to particle interactions. It explains the general formula for mechanical wave speed, involving force and inertia factors. The tutorial covers transverse waves on a string, longitudinal waves in solids, and gases, detailing the specific factors affecting their speeds. It also discusses how wave speed and wavelength change when transitioning between media, while frequency remains constant. An example problem involving a whale wave in seawater is solved to illustrate these concepts.

What primarily determines the speed of a wave in a medium?

• The wave's amplitude

• The color of the wave

• The medium's properties

• The wave's frequency

In a transverse wave on a string, what does the wave speed depend on?

• The string's color

• The string's tension and mass per unit length

• The string's length

• The string's width

What symbol is commonly used to represent mass per unit length in the context of transverse waves?

• T

• Rho

• Mu

• Lambda

For a longitudinal wave on a solid rod, what is the wave speed related to?

• The rod's color

• The rod's temperature

• The force and linear density

• The rod's width

Which term is used to describe the force factor in longitudinal waves in gases or solids?

• Shear modulus

• Bulk modulus

• Young's modulus

• Elastic modulus

What happens to the wavelength of a wave when it moves into a medium where its speed increases?

• The wavelength remains the same

• The wavelength decreases

• The wavelength increases

• The wavelength becomes zero

When a wave transitions between media, which property remains unchanged?

• Speed

• Amplitude

• Wavelength

• Frequency

In the example of a whale emitting a wave, what is the bulk modulus of seawater given?

• 1.4 times 10 to the 3rd newton per meter squared

• 2 times 10 to the 5th newton per meter squared

• 1.025 times 10 to the 3rd newton per meter squared
