Physics

2. when 2 waves overlap in such a way that they combine to create a larger wave
3. the complete range of all types of radiation that has both electric and magnetic fields and travels in waves
5. waves in which the direction of propagation aligns with the direction of vibration of the medium
7. the spreading out of waves as they pass through an aperture or around objects
8. the increase or decrease of frequency of sound, light or other waves as the source and observer move towards or away from each other
9. the phenomenon of bouncing back of the rays of light when they fall on an obstacle
12. the distance a wave travels in a given amount of time
13. the bending of light or sound as it passes through something like a wall(sound) window (light)
14. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
15. the number of waves that pass a fixed point in unit time

1. when 2 waves overlap in such a way that they cancel each other out
4. a material that moves energy or light from one substance to another, or from one location to another, or from one surface to another
6. a measurement of the amount of energy transferred by a wave
10. the transmission of energy through oscillating electric and magnetic fields at the speed of light
11. a wave vibrating at right angles to the directions of its propagation
