Question 1 (3 points)
(11.10_q1) which kind of wave brings us the suns energy thru the vacuum of outer space?

question 1 options:

sound waves

mechanical waves

electromagnetic waves

surface waves

question 2 (3 points)
(11.10_q2) what is the relationship between a reflected wave's "angle of incidence" and "angle of reflection"?

question 2 options:

those 2 angles add up to 180 degrees

those 2 angles are always equal

those 2 angle add up to 90 degrees

the "angle of reflection" minus the "angle of incidence" equal 45 degrees

question 3 (3 points)
(11.10_q3) electromagnetic waves can refract. refraction is how a prism separates white light into its individual colors. refraction occurs when light at a non-right angle goes into a new transparent medium with a different index of refraction and

question 3 options:

the transparent medium slows down the speed of light

the transparent medium acts like a lens and make an image seem bigger

the transparent medium acts like a mirror

question 4 (3 points)
(11.10_q4) mechanical waves are

question 4 options:

propagated by the motion of the medium particles

propagated by a good pr group

able to travel thru a vacuum

question 5 (3 points)
(11.10_q5) in a longitudinal wave, like a sound wave, the medium particles

question 5 options:

move back and forth perpendicular to the direction of the wave

move back and forth parallel with the direction of the wave

move with the wave all the way thru the medium

move in little circles

question 6 (3 points)
(11.10_q6) waves do not convey the medium particles which propagate them. but waves do carry 2 things. what are the 2 things?

question 6 options:

energy and information

mass and volume

protons and neutrons

question 7 (3 points)
(11.10_q7) which of the following is an example of frequency?

question 7 options:

10 seconds to complete 1 wave cycle

15 cm between wave crests

wave traveling at 5 cm/s

12 complete wave cycles in 1 second

question 8 (3 points)
(11.10_q8) the meeting of 2 wave crests in the same place and time is called "constructive interence" and it results in

question 8 options:

the absence of any wave

a huge wave, because the 2 waves multiply each other

a bigger wave because the 2 waves add together.
