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