Across
  1. 5. It’s a bending of a wave as it passes on a barrier with an obstacle.
  2. 6. It is an electric current flowing in one direction only.
  3. 8. is a Parallel motion, back and forth motion.
  4. 10. It receives signals.
  5. 14. It refers to the traveling pattern of motion exhibited by a wave, combining both oscillatory motion and forward motion.
  6. 16. He determined that penicillin had an antibacterial effect on staphylococci and other gram-positive pathogens.
  7. 17. It is a shift in the direction of a wavefront at the interface of two distinct media, causing the wavefront to return to the medium from which it came.
  8. 18. It has a mass of 1.673 x 10-27kg.
  9. 20. Switching direction back and forth
  10. 21. He proposed the Corpuscular theory.
  11. 25. It has a mass of 1.675 x 10-27kg
Down
  1. 1. It is the gravitational force acting between two bodies of unit mass, kept at a unit distance from each other.
  2. 2. He proposed the wave theory of light
  3. 3. It has a mass of 9.109 x 10-31kg.
  4. 4. The bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another.
  5. 7. is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
  6. 9. Two waves interact/have an intersection pattern.
  7. 11. He proposed that light waves were transverse (vibrating at right angles to the direction of travel), rather than longitudinal (vibrating in the direction of travel).
  8. 12. states the rotation across a conductor is directly proportional to the current having through it, propelled I prompted all physical entities) the temperature remains constant.
  9. 13. Light travels in straight light until the light strikes an object, then it can reflect, refract absorb and
  10. 15. During the mid-18th century, electricity was already a well-known phenomenon.
  11. 19. Detects a small amount of current in the circuit.
  12. 22. The displacement of the crest to crest/ Trough to Trough
  13. 23. The highest point in the wave train.
  14. 24. Force of attraction/repulsion of the two electrically charged parts is directly proportional.
