How are electromagnetic waves affected as the frequency of the waves increases? a) energy and wavelength increase b) energy and wavelength decrease c) energy decreases, wavelength increases d) energy increases, wavelength decreases

As the frequency is how many waves pass a fixed point in certain amount of times. This means that the waves get closer together and, therefore, the wavelength decreases. It also means that the wave has more energy.

D) Energy increases, wavelength decreases

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
