What kind of spring waves travel in a straight line?
What is compression waves
100
What color is sunlight and what evidence do you have to back up your answer?
What is White. White light has all color and when looking outside through the spectroscope all colors or the rainbow were reflected.
100
Using the red laser we pointed the laser toward a mirror, what was the ray called that hit the mirror?
What is an incident ray
100
if a person had a pulse of 12 beats in 15 seconds what would the pulse per minute be?
What is 48 beats
100
Why did the first image (without the pinhole) appear as a white blotch?
1. The hole was not creatively made
2. There were too many light waves entering the hole
3. The paper absorbed the white light
What is Too many light waves entered the hole
200
Besides Compression waves we made these waves with our springs
What is Transverse Waves
200
Some objects reflect color, others reflect but also do this to colors?
What is absorb
200
When we created the laser maze the initial ray hit a mirror and then it was redirected to another mirror. What is the name of the ray that was directed toward the next mirror?
What is reflected ray
200
If a person had a pulse of 72 beats per minute, what would the frequency be?
What is 1.2 beats/second
200
Why did the image get larger as you moved the screen closer to your eye?
What is As light rays traveled the angles grew large, enlarging the image
300
What are the 4 main parts of a Transverse wave?
What is Crest, Trough, Node, Amplitude
300
What is the range of wavelengths a human eye see:
200-600
500-1000
400-700
What is 400-700
300
When we used a green laser and we also used a plastic container full of water. When the laser went through the plastic and water it bent. What is that ray called?
What is refracted ray
300
Animals have 1-5 color receptors, how many do humans have?
What is 1-3
300
Why did the light filament appear flipped on the screen?
What is Light rays traveling in a straight line from below the pinhole traveled upwards on the screen and the ones above the pinhole traveled toward the bottom of the screen, inverting the image.
400
How do you measure the wavelength of a Transverse wave?
What is Measure from Crest to nearest Crest, or Trough to Trough or Node to like Node
400
How many color receptors do humans have?
What is 1-3
400
When you made the mirror maze you learned that the incident angle is:
greater than or equal to the reflected angle
What is equal to
400
When an earthquake occurs there are two waves that travel through the earth, P waves and S waves. What kind of waves are they?
What is Transverse and Compression
400
How is the pinhole in the box like the pupil in our eye?
What is like the pinhole light rays entering the pupil and through the lens are inverted and placed on the retina.
500
If the wavelength of wave A is 20 cm. and the wavelength of wave B is 40 cm. which would have the greatest frequency?
What is Wave A
500
What does a spectroscope tell you about a light?
What is visible light waves and wavelengths of that light. It is like an individual fingerprint for each light.
500
What is unique about the wave patterns of a laser beam?
What is the amplitude and wavelength are identical.
500
What is one wave that helps us with our health?
a. infrared
b. Radio
c. Gamma
What is Gamma
500
If you put a red filter in front of the pinhole on the box what would happen? be specific
What is The image would turn red, all other colors were being absorbed by the red filter so only red would be reflected.
