The video introduces the concept of waves, explaining that they are disturbances transferring energy. It distinguishes between mechanical waves, which require a medium, and electromagnetic waves, which can travel through a vacuum. The video describes wave movement, including transverse and longitudinal waves, and explains how to measure wave energy through wavelength and amplitude. It concludes with a call to action for further learning materials.

What is the primary function of waves in physics?

• To transfer energy

• To create sound

• To generate light

• To move objects

Which type of wave requires a medium to travel through?

• Longitudinal waves

• Transverse waves

• Mechanical waves

• Electromagnetic waves

Why can't sound waves travel in space?

• They are blocked by magnetic fields

• There is no light in space

• They require gravity to move

• There is no medium for them to travel through

Which of the following is NOT an example of a mechanical wave?

• Sound wave

• Ocean wave

• Seismic wave

• Radio wave

What allows electromagnetic waves to travel through a vacuum?

• They are carried by water

• They are pushed by wind

• They move through charged particles

• They rely on air molecules

Which of the following is a type of electromagnetic wave?

• Seismic wave

• Sound wave

• Ocean wave

• X-ray

How do transverse waves move?

• In a circular motion

• Up and down as they move forward

• Side to side

• In a zigzag pattern

What is the main difference between transverse and longitudinal waves?

• Transverse waves move energy up and down, while longitudinal waves move energy in the same direction

• Transverse waves require a medium, while longitudinal waves do not

• Transverse waves are slower than longitudinal waves

• Transverse waves are only found in water

What does wavelength measure in a wave?

• The color of the wave

• The speed of the wave

• The distance between wave peaks

• The height of the wave

What does a higher amplitude indicate about a wave?

• It has more energy

• It is slower

• It has less energy

• It is quieter
