Karten in diesem Stapel (15)
- 1What is a boundary?A place where TWO things meet
- 2What is the incident ray?The light ray that arrives at the boundary?
- 3What angle is the angle of incident the same as?The angle of reflection
- 4What does refraction mean?Change direction
- 5What is a converging lens?Where parallel rays of light converge/move closer :) ooooh la la
- 6What does the focal point mean?The point where all the rays meet :D :D
- 7What does the objective lens do?It converges to form a real image
- 8What does the eye piece lens do?So the image can be seen, and it also magnifies the image
- 9What kind of telescope uses a concave mirror?Reflecting telescope? (Remember that a mirror is a REFLECTION of you) see what I did there ;)
- 10How did Ritter discover ultraviolet radiation?He exposed strips of silver chloride coated paper to each colour in the visible light spectrum using a prism,
and times how long it took to turn black
The strips changed quickest when exposed to light nearer the blue end of the spectrum
He saw the quickest change was just past the violet part of the spectrum - 11What are microwaves used for?Cooking, satellite communication, mobile phones :))) THANKYOOOUUU MICROWAVESSS!!!
- 12What are the dangers of UV radiationCauses skin cancer and eye damage
- 13What is infrared used for?Thermal imaging, optical fibres transmitting data, cooking, grills, toasters, computers, remote controls
- 14What are the THREE types of ionising radiation?Alpha, Beta, Gamma
- 15What does ionising radiation cause atoms to do?Lose electrons
