c) 1. Plank’s hypothesis states that the energy was quantized.
2. Light acts sometimes like a wave and sometimes like a particle.
3. In this phenomenon electrons are emitted when certain metallic materials
are exposed to light. This direct conversion of light into electrical energy which
happens almost immediately could not be explained by classical physics
according to which it would take an appreciable time for an electron to be
emitted. Applying Planck’s hypothesis, Einstein assumed that light or any
electromagnetic radiation was quantized. By considering light to be composed
of photons or quanta of energy, Einstein was able to successfully explain the
photoelectric effect.
18. 1) look; 7) to wear;
2) to catch; 8) say;
3) to magnify; 9) go, do;
4) cause; 10) calculate;
5) to monitor; 11) shake;
6) seek; 12) open, move.
19. 3. I believe them to be guilty.
4. I found him to be very lazy.
5. She pretended not to recognize him.
6. He expects them to come to the party.
7. He claims to have been abroad at the time of the robbery.
8. He expects to inherit a large house when his grandfather dies.
9. We discovered the argument to be false.
10. I agreed to come.
20. 2. I hate them to make fun of me.
3. I don’t trust them to settle my financial problems.
4. They forbid us to cross the street at a red light.
