Wave Interactions and Properties

The video tutorial by Jenny covers wave interactions, focusing on absorption, transmission, reflection, refraction, diffraction, and interference. It explains how waves interact with matter, change direction, and transfer energy. Examples include sound waves in a shower and light waves creating mirages. The video concludes with a summary of these concepts and encourages viewer engagement.

What are the three main ways waves interact with matter?

• Absorption, Diffraction, Reflection

• Transmission, Refraction, Interference

• Diffraction, Refraction, Interference

• Absorption, Transmission, Reflection

What happens during wave absorption?

• Waves bounce off a surface

• Waves change direction

• Waves pass through a material

• Waves transfer energy to a material

Why is your voice more powerful in the shower?

• The shower walls absorb the sound

• The shower walls reflect the sound

• The sound waves are transmitted through the walls

• The sound waves are refracted by the walls

What causes refraction of waves?

• Change in wave direction

• Change in wave speed

• Change in wave frequency

• Change in wave amplitude

What is a mirage?

• A refraction of light waves

• A reflection of light waves

• An interference of light waves

• A diffraction of sound waves

What is diffraction?

• Waves bending around an object

• Waves changing speed

• Waves passing through a medium

• Waves bouncing off a surface

What is the principle of superimposition?

• The sum of wave displacements

• The sum of wave frequencies

• The sum of wave speeds

• The sum of wave amplitudes

What is constructive interference?

• No change in wave displacement

• Waves cancel each other out

• Increase in wave displacement

• Decrease in wave displacement

What is the law of reflection?

• Angle of incidence equals angle of refraction

• Angle of incidence equals angle of reflection

• Angle of refraction equals angle of reflection

• Angle of incidence is greater than angle of reflection

What happens during wave interference?

• Waves are reflected off a surface

• Waves are absorbed by a medium

• Waves pass through each other

• Waves combine to form a new wave
