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