Energy Crossword

2. A wave that moves in the same direction as the direction in which the particles are vibrating e.g. sound waves
6. Describes how high or low a sound is and it depends on how fast or slow an object is vibrating
9. When light bounces off an object
10. An absence of light. If light cannot get through an object, the surface on the other side of that will have less light reaching it
12. The angle at which the light enters
14. It is curved outwards like the surface of a sphere
15. The transfer of energy in a motion that is perpendicular to the direction the wave is travelling e.g. radio and light waves
16. An energy source that travels in waves, and we can see these wavelengths of light in different colours

1. The bending of light as it passes from one transparent substance into another
3. The distance from the centre line (or the still position) to the top of a crest (the top most part of a wave)
4. The number of waves that pass a given point in one second, measured in Hertz
5. A disturbance that transfers energy from one place to another in a regular and organised way
7. A force that can cause things to move or the ability to do work e.g. potential, kinetic, thermal, electrical, chemical, nuclear
8. A shape that curves inward or is hollowed out
11. The distance between a point on one wave and the same point on the next wave
13. Type of energy made by vibrations as an acoustic wave through a medium such as a gas, liquid or solid
