Waves and Energy Transfer in Physics

The video tutorial introduces key vocabulary for the wave unit, explaining the concepts of waves, mediums, mechanical and electromagnetic waves, and their movements. It covers the parts of waves, including crest, trough, amplitude, wavelength, and frequency, emphasizing the importance of understanding these terms for the unit's success.

What is the primary function of a wave?

• To create sound in a vacuum

• To transfer energy from one place to another

• To transfer matter from one place to another

• To change the state of matter

Which of the following is true about mechanical waves?

• They are the same as electromagnetic waves

• They require a medium to propagate

• They do not require a medium

• They can travel through a vacuum

Which of the following is NOT a type of electromagnetic wave?

• Sound wave

• Radio wave

• Ultraviolet

• X-ray

Which type of wave movement involves energy traveling perpendicular to the wave direction?

• Longitudinal

• Circular

• Transverse

• Diagonal

Which wave movement is only found in mechanical waves?

• Electromagnetic

• Circular

• Longitudinal

• Transverse

What is the highest point of a transverse wave called?

• Amplitude

• Crest

• Compression

• Trough

What is the term for the distance between two consecutive crests in a wave?

• Amplitude

• Frequency

• Wavelength

• Compression

In a longitudinal wave, what is the term for the area where particles are closest together?

• Compression

• Crest

• Trough

• Refraction

How are frequency and wavelength related in wave behavior?

• They are always equal

• They are not related

• As frequency increases, wavelength increases

• As frequency increases, wavelength decreases

What does the term 'refraction' refer to in the context of waves?

• The compression of particles in a wave

• The highest point of a wave

• The bending of waves as they pass through different mediums

• The expansion of particles in a wave
