What is violet, indigo, blue, green, yellow, orange, and red.
100
Which visible color has the shortest wavelength?
What is violet
100
What is wave speed?
What is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period.
100
How do you determine the frequency of a wave
What is divide the velocity of the wave, V, by the wavelength converted into meters, λ, in order to find the frequency, f.
100
Which part of the electromagnetic spectrum has high enough energy to cause damage to eyes and skin, and sometimes even cancer?
What is ultraviolet rays

Bill counts 5 waves on a pond in 10 s. The distance between them is 80 cm. What is their speed?
What is 40 cm/s
200
If you're moving from gamma rays to microwave, describe how the energy level changes
What is decreases
300
Which electromagnetic waves have the shortest wavelengths and highest frequencies?
What is gamma rays
300
Which of the following wavelengths can easily penetrate the Earth's atmosphere?
Radio waves or Microwaves
Explain your answer.
What is the Earth's atmosphere is transparent to some wavelengths of microwave radiation, but not to others. The longer wavelengths (waves more similar to radio waves) pass through the Earth's atmosphere more easily than the shorter wavelength microwaves
300
If a wavelength is about 1.75 meters and its frequency is 2.0 HZ, what would its speed be?
What is 3.5 m/s
You times 1.75 meters with 2.0 frequency
300
What is a wavelength and its formula.
What is the distance between crests of a wave. The formula is equal to the velocity of the wave, divided by the frequency.
300

______________ waves occur when the motion of the medium is at right angles (perpendicular) to the direction of the wave.
What is transverse waves
400
