Semester Exam Waves

Front

What happens to sound waves when they are absorbed?

Back

Sound waves lose energy and are not reflected back.

Front

What does high amplitude in a wave indicate about its energy?

Back

High amplitude indicates that the wave has high energy.

Front

How do you calculate the speed of a wave?

Back

Speed = Frequency x Wavelength.

Front

What is the frequency of the musical note A above middle C?

Back

440 Hz.

Front

What is the electromagnetic spectrum?

Back

The range of electromagnetic waves ordered by increasing frequency.

Front

What type of wave can travel without a medium?

Back

Electromagnetic wave.

Front

What is a mechanical wave?

Back

A wave that requires a medium to travel through.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases, and vice versa.

Front

What is refraction in the context of waves?

Back

Refraction is the bending of waves as they pass from one medium to another.

Front

What is reflection in wave behavior?

Back

Reflection is when waves bounce back after hitting a barrier.
