Longer wavelengths will have frequencies, and shorter wavelengths will have frequencies.

Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies.

Wavelength is the distance between two successive crests or trough in a waveform.

Wavelength is measured in meters, and the value can be obtained by diving the speed of the wave by its frequency.

Frequency is the number of cycles of a wave per unit time of motion.

Frequency, wavelength and velocity is related as shown below;

where;

From the relationship above, a longer wavelength will result in a lower frequency while a shorter wavelength will result in a higher frequency.

Thus, we can conclude that, longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

heat is transmitted by radiation
