Which of the following describes the relationship between frequency and wavelength?

as frequency increases, wavelength increases.

as frequency decreases, wavelength decreases.

as frequency increases, wavelength decreases.

as frequency increases, wavelength is unaffected.

As frequency increases, wavelength decreases.

Explanation:

V = f λ

V is the speed

F is the frequency  

λ is wavelength  

If we look at the above equation, it can be deduced that frequency and wavelength are inversely proportional to one another. This means that if the frequency increases the wavelength decreases and vice versa is the case

Frequency is the number of cycles made per second. Wavelength is the distance between two crests or troughs.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
