1. A wave had a wavelength of 5m and speed of 15m/s, what is the frequency 2. Red light has a longer wavelength than violet light, which one has the greater frequency?(hint they both travel at the same speed)

3. If speed of a longitudinal sound wave is 340m/s and the frequency is 1000 Hz, what is the wavelength?

Frequency is 3HZ.

Explanation:15/5 =3

Violet has more frequency

Wavelength is 340000m.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
