Describe the relationship between the wavelength and frequency of electromagnetic waves.

The relationship between frequency and wavelength is that they are inversely proportional.

Explanation:

For instance, we can treat a wave with a higher frequency on a rope faster than before. While doing this, we'll notice that the wavelength will become shorter. Thus, the relation between frequency and wavelength do exist, so let’s find out what exactly is this relationship.

Period (T) is another entity that can be used to describe a wave. It is defined as the time taken to complete oscillation. However, since frequency determines the number of times a wave oscillates and it can be expressed as,

f = 1/t

Now, since a wave undergoes one oscillation during one period, every point on the wave returns to the same value after one period. This is as a result of every session of oscillation travelling a distance of a wavelength in one period to finish.

Now, wave speed (v) is defined as the distance travelled by a wave per unit time. If we consider that the wave travels a distance of one wavelength in one period, it is given by the formula ;

ν=λ/T

Where λ is wavelength.

As we know that, T = 1/f, hence we can express the above equation as,

V = f λ

Now, at a value of wave velocity, as the frequency is increasing, the wavelength would be decreasing and this implies the relationship between frequency and wavelength is that they are inversely proportional.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

your answer is c! hope this : )
