Wave Parts
This is the top of the wave
What is a crest?
The waves of the Electromagnetic Spectrum are all which type of wave?
What is a transverse wave?
The bouncing of light off a reflective surface
What is reflection?
Used to examine most areas of the body. Mainly bones and joints
What are x-rays?
Makes reflected images larger
This is the distance between two crests or two troughs
What is a wavelength?
What do all the waves in the Electromagnetic Spectrum carry?
What is Energy?
The bending of light
What is refraction?
What are gamma rays?
Every wave, regardless of type or medium transfers this
What is energy?
This is the bottom part of a wave
What is a trough?
How do the waves in the Electromagnetic Spectrum differ?
What is wavelength? or What is frequency? or What is energy?
The name given to the ray which is being reflected
Used for detecting fake bank notes in shops, killing microbes and sterilising
What are ultra violet waves?
A lens that focuses light
What is a convex lens?
This is the vertical distance between the middle of the wave and a crest or trough
What is an amplitude?
Which waves carry the most energy?
What are gamma rays?
Any substance that a wave can travel through
Used for cooking, speed cameras and radars
What are microwaves?
The name given to the ray that hits the surface
This is the number of waves passing a point in one second
What is frequency?
Which waves are easily detected with our eyes?
The line perpendicular to the reflecting surface
What is the normal?
Used for communication
The angle of incidence equals the angle of reflection
What is the Law of Reflection?
