Which accurately describes the behavior of sound and light in the vacuum of space?
a.
a vacuum is a type of medium. sound, which is a type of mechanical wave and requires a medium, will travel there. light, which travels as electromagnetic waves and does not require a medium, will not travel there.
b.
a vacuum does not contain a medium. light, which is a type of mechanical wave and requires a medium, will not travel there. sound, which travels as electromagnetic waves and does not require a medium, will travel there.
c.
a vacuum is a type of medium. sound, which is a type of mechanical wave and does not require a medium, will travel there. light, which travels as electromagnetic waves and does require a medium, will also travel there.
d.
a vacuum does not contain a medium. sound, which is a type of mechanical wave and requires a medium, will not travel there. light, which travels as electromagnetic waves and does not require a medium, will travel there.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
