A coiled spring with coils that are closely spaced then widely then closely then widely then closely, ending with a yellow line labeled 1 second. What is the frequency of this wave?

The frequency of the wave is 2Hz.

Explanation:

The frequency of a wave is the number of waves that pass a fixed point in a given amount of time. It can be measured by counting the number of crests that pass the point in a given time period. The higher the number is, the greater is the frequency of the wave.

So, by counting the number of times the coils in the spring are widely spaced, which is 2 times in 1 second, we get the frequency of the wave.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
