Which electromagnetic wave has the shortest wavelength? Which electromagnetic wave would have a wavelength approximately the size of the tip of a pencil?

Which electromagnetic wave has the longest wavelength?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

The ph is the a. independent variable b. the dependent variable c. control group
