Question

1. circle the wave above that has the higher amplitude.
2. which electromagnetic wave has the highest frequency and shortest wavelength?

a) x - rays
b) gamma rays
c) microwaves
d) visible light

1. the two pictures below show waves created by throwing rocks into a pond. circle the wave that has a higher amplitude.
2. when liquid water turns into water vapor, the molecules move

a) faster
b) slower
c) both answers are correct

Explanation:

Step1: Recall amplitude definition

Amplitude is the maximum displacement from the equilibrium position. In the first - set of waves, Wave 2 has a larger displacement from the equilibrium line, so it has a higher amplitude.

Step2: Recall electromagnetic - wave properties

In the electromagnetic spectrum, gamma rays have the highest frequency and the shortest wavelength among the given options.

Step3: Analyze pond - wave amplitude

For the pond waves, the wave with more pronounced ripples (larger displacement from the calm - water state) has a higher amplitude. The left - hand wave in the pond wave picture has larger ripples, so it has a higher amplitude.

Step4: Recall molecular motion in phase change

When liquid water turns into water vapor (a process of evaporation), the molecules gain more kinetic energy and move faster.

Answer:

1. Wave 2
2. B. Gamma rays
3. The left - hand wave in the pond wave picture
4. A. Faster
