Reflection

Refraction

Diffraction

absorption

interference

standing wave

Resonance

Reflection:

The phenomenon of a propagating wave (light or sound) being thrown back from a surface

Sentence: Your reflection is what you see in the mirror. Other things that bounce back at you are also reflections — light waves, sound waves, even your thoughts.

Refraction:

Definition: The change in direction of a propagating wave (light or sound) when passing from one medium to another

Sentence: Refraction is the bending of light or sound as it passes through something like a wall (sound) or a window (light).

Diffraction:

Definition: When light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands

Sentence: Diffraction is the process of light bending around an obstacle or spreading out after it moves through a small space. If you study physics, you'll learn about the diffraction of light waves.

Absorption:

Definition: (chemistry) a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid

Sentence: Absorption describes the process of absorbing or soaking up something: Sponges are good at water absorption; dark colors are better for heat absorption.

Interference:

Definition: The act of hindering or obstructing or impeding

Sentence: Interference is something that is in your way. If the sound of your sister's band practicing keeps you from getting your homework done, that’s interference.

Standing wave:

Definition: A wave (as a sound wave in a chamber or an electromagnetic wave in a transmission line) in which the ratio of its instantaneous amplitude at one point to that at any other point does not vary with time

Sentence: A bubble, trapped and held in a fixed position by an acoustic standing wave, begins to move erratically if a threshold wave amplitude is exceeded. The longitudinal standing wave is synchronously forced and resonated while the cross-wave is not resonant and is of higher order in amplitude.

Resonance:

Definition: Having the character of a loud deep sound; the quality of being resonant

Sentence: If you have a loud, deep voice, then your voice has resonance, and if your words are powerful and meaningful, then your words have resonance, too. Something with resonance has a deep tone or a powerful lasting effect.

I hope this helps! :)

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 =
