True or False? All of an element's spectral lines must match up to the spectral lines of a star in order for that element to be present.
True
100
Which subatomic particle exists in energy levels and can jump from one level to another?
electron

Blue light is observed. What is its most likely wavelength? 
470 nm
100
A light ray strikes a mirror at an angle of 25o. What is the angle of reflection?
25o
100
True or false? If the incident ray is not on an angle, there is no reflection or refraction.
True
200
What does spectroscopy tell us about stars?
The elements present in the star.
200
Which jump would RELEASE the most amount of energy?
A
200
Compared to x-rays, infrared light has a _______ wavelength.
Longer
200
When we observe an object in a cup of water, why does the object appear to be at a different position than it really is.
Refraction bends the light in the cup of water
200
What is the law of reflection?
Angle of incidence = Angle of reflection
300
Why does each element produce its own unique pattern of spectral lines?
The energy levels in the atom of each element is unique (different distances between them = different energy released)
300
An electron releases blue light, while another releases red light. Which light is produced by a larger energy-level drop?
Blue
300
Scientists use different types of waves to see different details of space. A new telescope can use three types of waves that all have less energy than visible light. Which types of waves does this telescope use?
Radio waves, microwaves, infrared
300
Which direction is light refracted when it travels from glass to air?
Away from the normal
300
Which wave has more energy?
Wave 1
400
A student compares a star to the hydrogen reference. Two of hydrogen’s three spectral lines match the star. What should the student conclude?
Hydrogen is not present in the star
400
What color of light is most likely to be released when an electron releases a large amount of energy when it falls to a lower energy level.
Violet, purple, or blue
400
When the frequency of a wave is increased, what happens to its wavelength?
It decreases
400
How does the density of the medium affect the speed of light that travels through it?
The more dense, the slower it travels. The less dense, the faster it travels.
400
When light strikes the boundary between two different materials, some light reflects. What happens to the light that enters the second material at an angle?
It is refracted
500
Which gases are present in the unknown mixture?
Gas A & D
500
An electron falls from energy level 5 to energy level 4. Describe the wave (energy, frequency, wavelength) that is released from this fall. 
Low energy, long wavelength, low frequency
500

500
Draw the reflected ray, no refraction line, & refracted ray.
