Unit 3 Review: Waves

Front

What happens to the frequency of electromagnetic waves as wavelength increases?

Back

The frequency decreases.

Front

Which type of electromagnetic radiation has the longest wavelength?

Back

Radio waves.

Front

How does the temperature of a medium affect the speed of sound?

Back

As the temperature of the medium decreases, the speed of sound decreases.

Front

What is a key reason an experiment cannot be replicated?

Back

The procedure and results were not explained in detail.

Front

In which medium do light waves travel the fastest: air, water, or glass?

Back

Air.

Front

What is the relationship between wavelength and frequency in waves?

Back

They are inversely related; as one increases, the other decreases.

Front

What is the speed of sound in desert air?

Back

358 meters per second (m/s).

Front

What is the speed of sound in polar air?

Back

330 meters per second (m/s).

Front

What is the definition of electromagnetic radiation?

Back

Electromagnetic radiation is a form of energy that travels through space at the speed of light.

Front

What is the effect of adding fertilizer to plant growth in an experiment?

Back

Plants that receive fertilizer and water grow faster than those that only receive water.
