A student is performing an experiment comparing sound and light waves. The student gathers the following data.

Speed of
Sound (m/s)
3200 m/s
1500 m/s
346 m/s
What conclusion does the student most likely make
based on this data?
Light waves always travel the same speed, however,
the speed of sound is determined by the medium that
it travels through
All sound waves always have the same energy, so the
temperature of the medium does not affect wave
speed.
O Light needs to vibrate particles, so it travels fastest in
tightly packed solids, while sound does not need a
medium, so it travels fastest in a gas.
O Tightly packed particles in solids slow down the light
waves; however, sound waves make particles bounce
into each other, so they travel faster in solids.

Nova: secrets of the sun - video guide worksheet due tomorrowfront side (photo up top)back side (below of the following)1) a mass ejection is a wave of billions of tons of electrically charged particles.2) the sun is so huge, a earths could fit inside of it.3) the surface of the sun seems to vibrate because the sun generates waves4) using geoseismology or helioseismology, we can see the physical process under the sun's surface.5) the thickest layer of plasma in the sun is a region called the zone.6) the thinner plasma in the convection zone makes the move in a more ordered way.7) rising and sinking plasma created a mesmerizing structure called 8) the sdo revealed tornadoes or volcanoes, hundreds of miles high, on the surface of the sun9) sdo allows scientists to see sunlight across a range of 10) the earth's field protects us against threats from the sun.11) the plasma layers beneath the surface act as a which gets denser towards the core. 12) can light up along the paths of the magnetic field, making them visible. 13) the sun's the corona, is made of plasma that reaches over 3 million degrees.14) a sun spot is dark because it is cooler or warmer than its surroundings15) magnetic outbursts are more common during the period called solar
