WAVE BASICS
The disturbance that transfers energy from place to place without transferring matter.
3X THE POINTS VALUE IF CORRECT!
What is a wave?
A material that allows light to pass through clearly so objects can be seen through it.
What is transparent?
The number of waves that pass a point each second.
What is frequency?
The part of the electromagnetic spectrum humans can see.
What is visible light?
When a wave bounces off a surface and changes direction.
What is reflection?
The distance between two corresponding parts of a wave such as crest to crest.
What is wavelength?
A material that does not allow light to pass through.
What is opaque?
How high or low a sound seems.
What is pitch?
Electromagnetic waves with the longest wavelengths used in communication.
2X THE POINT VALUE IF CORRECT!
What are radio waves?
The bending of waves as they pass through an opening or around an object.
DOUBLE JEOPARDY!!!
What is diffraction?
The height of a wave from rest position to crest or trough.
What is amplitude?
A lens or mirror that curves inward.
2X THE POINT VALUE IF CORRECT!
What is concave?
A unit used to measure sound intensity.
DOUBLE JEOPARDY!!!
What is a decibel?
Electromagnetic waves that we feel as heat.
What are infrared rays?
When a wave bends as it passes from one medium to another.
What is refraction?
A wave that requires a material to travel through.
What is a mechanical wave?
The point where light rays meet after reflection or refraction.
What is the focal point?
How loud or soft a sound appears.
What is loudness?
Very high-energy waves used in medical imaging.
What are X-rays?
When two waves combine to form a new pattern.
What is interference?
A wave where particles move perpendicular to the direction the wave travels.
What is a transverse wave?
A material that lets some light through but scatters it.
What is translucent?
When an object vibrates strongly at its natural frequency due to matching vibrations.
What is resonance?
The highest-energy waves in the electromagnetic spectrum.
What are gamma rays?
The bending and spreading of waves around obstacles or openings.
What is diffraction?
