Light energy example:
Visible light, Infrared radiation, ultraviolet light, microwaves, radio waves, x-rays, or gamma rays
What type of wave is a sound wave?
Mechanical
What term describes a disturbance that transfers energy from one place to another?
Wave
What is a mechanical wave?
A wave that requires a medium (solid, liquid, or gas) to travel
What is an electromagnetic wave?
A wave that can travel through a vacuum and does not need a medium.
What is the term for the bending of light when it passes from one medium to another?
Refraction
What is a sound wave?
A mechanical wave that requires a medium to travel
Which of the following is the measure of the distance between two consecutive crests or troughs of a wave?
Wavelength
Which of these is an example of a mechanical wave?
Which of the following is an example of an electromagnetic wave?
Light wave
If a light wave has a high frequency, what happens to its energy?
It increases.
How does sound travel through the air?
By vibrating air molecules
What is the term for the highest point of a wave?
Crest
What is the term for the part of the wave where the particles of the medium are closest together in a longitudinal wave?
Compression
Which of these types of electromagnetic waves have the shortest wavelength?
Gamma rays
Which color of light has the longest wavelength?
Red
What determines the pitch of a sound?
Frequency of the wave
What term refers to the wave that travels in a direction perpendicular to the vibration of the particles?
Transverse wave
What happens when a mechanical wave moves from one medium to another (like from air to water)?
The waves changes speed and direction.
What do all electromagnetic waves have in common?
They all travel at the same speed in a vacuum.
When white light passes through a prism, it splits into different colors. What is this phenomenon called?
Dispersion
What is the term for the bouncing back of sound waves when they hit a surface?
Reflection
What term describes the bending of a wave as it passes from one medium to another?
Refraction
What is the relationship between the amplitude of a mechanical wave and the energy it carries?
The higher the amplitude, the more energy it carries
What happens to the energy of an electromagnetic wave as its frequency increases?
The energy increases.
