Wave Properties and Behavior

This video tutorial covers the basics of waves, including their properties such as amplitude, wavelength, and frequency. It distinguishes between transverse and longitudinal waves and explains how waves transfer energy without moving matter. The tutorial also explores wave behaviors like transmission, absorption, and reflection, with a focus on refraction and reflection. The electromagnetic spectrum is introduced, highlighting visible light and its properties. Finally, the video explains how convergent and divergent lenses affect light waves.

What is the primary function of waves?

• To change color

• To transfer matter

• To transfer energy

• To create sound

Which part of a wave is measured from the rest position to the top of the wave?

• Wavelength

• Frequency

• Amplitude

• Crest

What distinguishes transverse waves from longitudinal waves?

• Longitudinal waves vibrate perpendicular to the direction of travel

• Transverse waves vibrate perpendicular to the direction of travel

• Longitudinal waves have crests and troughs

• Transverse waves have compressions and rarefactions

Which of the following is an example of a longitudinal wave?

• Radio wave

• Sound wave

• Water wave

• Light wave

What happens to a wave when it is absorbed by a material?

• It changes direction

• It passes through the material

• It bounces back

• It is absorbed and does not pass through

What is the term for the change in direction of a wave as it passes from one medium to another?

• Reflection

• Absorption

• Diffraction

• Refraction

What is the angle called at which a wave enters a new material?

• Angle of transmission

• Angle of reflection

• Angle of incidence

• Angle of refraction

What type of reflection occurs when light waves bounce off a completely flat surface?

• Diffuse reflection

• Specular reflection

• Absorptive reflection

• Refractive reflection

Which color of light has the highest frequency?

• Red

• Green

• Blue

• Yellow

What type of lens brings light waves together to a focal point?

• Absorptive lens

• Divergent lens

• Convergent lens

• Reflective lens
