Across
- 3. change in speed of sound during refraction
- 6. occur when the particles are somewhat pulled away from other particles creating a wider distance between particles
- 9. are waves that are usually created by pulling and pushing the material or medium
- 10. is the tendency of a material to maintain its shape
- 13. form when air particles or molecules of the medium are pushed creating lesser distance between particles
- 14. is the change in speed of sound when it encounters a medium of different density
- 16. Refers to the multiple reflections
- 17. sound travels slower in it
- 18. happens to have the lowest frequency and the least energy
- 20. is a special kind of refraction which provided us colors of light
Down
- 1. consists of waves of air particles
- 2. is the bending of light when it travels from one medium to another
- 4. Is needed to break the white light into different colors of light
- 5. Example of a reflected sound
- 7. The force applied per unit area
- 8. does not need a medium in order to propagate
- 11. is described as the mass per unit volume of the medium
- 12. Sound travels faster in it
- 15. the sluggishness of the atoms of a medium to maintain the absorbed energy before reemitting
- 19. brings about multiple reflection of sound
