Exploring Electromagnetic and Mechanical Waves

What is the primary difference between mechanical waves and electromagnetic waves?

• Mechanical waves require a medium to travel, while electromagnetic waves do not.

• Electromagnetic waves require a medium to travel, while mechanical waves do not.

• Mechanical waves carry energy, while electromagnetic waves do not.

• Mechanical waves can travel through a vacuum, while electromagnetic waves cannot.

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

• Light wave

• Sound wave

• Water wave

• Microwave

In a longitudinal wave, what is the term for the region where the wave is spread out?

• Compression

• Crest

• Trough

• Rarefaction

What is the term for the highest point of a transverse wave?

How do mechanical waves travel through solids compared to gases?

• They cannot travel through solids

• Faster in solids, slower in gases

• At the same speed in both

• Faster in gases, slower in solids
