Across
  1. 2. refers to various phenomena which occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle.
  2. 5. maximum extent of a vibration or oscillation, measured from the position of equilibrium
  3. 8. number of periods or regularly occurring events of any given kind in unit of time, usually in one second.
  4. 9. energy/ the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
  5. 10. a property of objects which can be transferred to other objects or converted into different forms
  6. 12. the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
  7. 13. distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
  8. 15. waves/also known as "l waves", are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave.
Down
  1. 1. is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.
  2. 3. throwing back by a body or surface of light, heat, or sound without absorbing it.
  3. 4. process or action by which one thing absorbs or is absorbed by another
  4. 6. wave/ are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.
  5. 7. natural agent that stimulates sight and makes things visible
  6. 11. Waves are characterized by wavelength, frequency, and the speed at which they move
  7. 14. waves/ is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave.
