Waves and Coastal Features

What is the difference between mechanical and electromagnetic waves?

• Electromagnetic waves are slower than mechanical waves.

• Mechanical waves can travel through a vacuum, unlike electromagnetic waves.

• Mechanical waves are transverse, while electromagnetic waves are longitudinal.

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

Name the three types of mechanical waves.

• Transverse waves, Longitudinal waves, Surface waves

• Sound waves

• Electromagnetic waves

• Circular waves

What are the two main parts of a wave?

• High and Low

• Crest and Trough

• Top and Bottom

• Peak and Valley

Explain the concept of wavelength in waves.

• The wavelength in waves is the distance between two consecutive points in a wave that are in phase with each other.

• Wavelength is the frequency of the wave

• The wavelength is the speed of the wave

• Wavelength is the amplitude of the wave

What is the amplitude of a wave?

• The amplitude of a wave is the measure of the speed of the wave

• The amplitude of a wave is the measure of the maximum disturbance in the medium from its equilibrium position.

• The amplitude of a wave is the measure of the wavelength of the wave

• The amplitude of a wave is the measure of the frequency of the wave

Define frequency in relation to waves.

• The amplitude of a wave

• The color of a wave

• The number of complete cycles of a wave that pass a given point in a specific amount of time.

• The speed of a wave

How are transverse waves different from longitudinal waves?

• Transverse waves do not transfer energy.

• Transverse waves oscillate perpendicular to the direction of energy transfer, while longitudinal waves oscillate parallel to the direction of energy transfer.

• Longitudinal waves oscillate perpendicular to the direction of energy transfer.

• Transverse waves oscillate parallel to the direction of energy transfer.

What causes waves to break near the shore?

• Moon phases

• Fish swimming near the surface

• Interaction between the wave crest and the ocean floor

• Underwater volcanoes

Name a coastal feature formed by wave erosion.

• Sea cliffs

• Mangrove forest

• Rocky shore

• Sand dunes

Describe how a wave-cut platform is formed.

• A wave-cut platform is formed by tectonic plate movement

• A wave-cut platform is formed through the erosion of a cliff face by wave action, resulting in the formation of a flat rocky platform at the base of the cliff.

• A wave-cut platform is formed by wind erosion

• A wave-cut platform is formed by volcanic activity
