This sound has high pitch, which means it has a higher frequency. This means when you hear the sound...

More waves hit your ears per second

Less waves hit your ears per second

All waves carry energy from one place to another, but some waves carry more energy than others. A leaf falling on water produces waves so small they are hard to see. An earthquake under the ocean can produce huge waves that cause great destruction. What affects the energy of a wave? Select the 3 that apply.

The energy in a wave is determined by amplitude, which is the distance from the rest position of a wave to the top or bottom.

Large amplitude waves contain more energy .

The energy in a wave is determined by frequency, which is the number of waves that pass by each second.

The medium (material) moving along with the wave.

One hertz is equal to:

all the cycles in the wavelength

The particles in cold air have less kinetic energy than the particles in warm air. this means that they collide less often and take longer to transmit a sound wave pulse. What is this an explanation of:

the speed of electromagnetic energy

Each wavefront expands in a sphere, spreading the energy across a larger area. This means that the energy per unit area of the wave decreases as it moves farther form its source, causing the loudness of the sound wave to decrease. This is an example of:

energy of the sound wave changing as it moves farther away from the source.

energy of the sound wave remaining constant as it moves farther away from the source.

energy of the sound wave increases as it moves farther away from the source.

How are Electromagnetic waves different from Mechanical waves?

EM waves can travel through the vacuum of space (without particles)

EM waves have very short wavelengths

EM waves transmit energy instead of matter

EM waves can change direction by reflection

Wavelength and Frequency are related in that...

when one increases, the other decreases (inversely proportional)

they both vary in an irregular pattern
