Explain the relationship between wavelength and frequency in the electromagnetic spectrum.

Answers

Answer:

The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength

Explanation:

The wavelength and frequency of an electromagnetic wave are inversely proportional to each other.

What is Wavelength and frequency?

Wavelength is the distance between any two identical points or adjacent crests in the adjacent cycles of a waveform signal which is propagated in space or along a wire. In the wireless systems, this length is usually specified in the units of meters (m), centimeters (cm) or millimeters (mm).

Frequency is the rate at which the current changes its direction per second time. Frequency is measured in the units of hertz (Hz), an international unit of measure where, 1 hertz is equal to 1 cycle per second of time.

The wavelength in an electromagnetic spectrum is inversely proportional to the frequency of the wave. The shorter the wavelength, the higher the frequency of the wave. Because, all light waves move at the same speed in a vacuum medium, the number of wave crests passing at a given spot in one second is determined by the wavelength of the wave.

Poems and Quos for People out there who are like me....Poem of Life:You can leave, but don't leave the world behind.Make your choices, choose smart and wise.Take time to live life to the fullest and the best, and breathe the sweet smell of life.You have your choices, you choose between, make the right one and you shall see.Life has surprises, life has its turns, but you must get through for you to live and experience.Read it when you need to, When times are hard and sad. With anger and pain, but always see yourself as number one, Do what you think is right for yourself and other, Even though some decisions you make will be for yourself.Strong:We are strong, we all carry great feelings for the ones we love, if they are not strong, help and carry them to the end. People need to be strong in times of need, or maybe just in general, people who are not strong need people who are, to help them lead the way, till both are equally strong, and together people and people, strong or weak either way can make great deeds in life, and immortal marks in the world. Trees:Leaves fall to the ground, like a old tree losing its memories,Sap drips on cars, and onto the ground, from the face of the tree, like its crying.It sways in the wind, trying to keep its balance, and to stay strong,The wind rustles through the branches and leaves, giving advice and messages,Carved scars, in the hard, tough bark of a tree.We, us people are trees of our own, as we grow old, we forget our memories, but we always make more, in time.We cry, and produce our feelings, and they drip, into or onto others.We sway, as we try to stay strong, and to keep our balance.And we produce advice and messages, from our minds, as we think, in deep thought.We are trees, strong, tall, structures, that live life, produce, and die off. Friends:There's this little thing called friendship.I experience it every day,And will always be thankful that I have friends,Because they have helped me along the way.A friend is a flashlight in the dark, or a somebody who will hold your hand in the dark,A rainbow after the storm,The sunshine after a cold, damp day,The glue when you are torn.I have friends I love like sisters and brothers.(I know they love me too.)They'll be there through thick and thin,For you must know that friendship can be true.Beauty:We don't understand the beauty inside so we criesAll the tears that fall from our eyesAnd the pain we try to hideA few know about our thoughtsAnd the scars on our body from the people who tauntWe want to stop 'this' only for some reliefBut with all the grief we feel within it's harder to stopThen it is to beginParents don't understand, And so they just shoutAnd make them feel even more worthless, And full of doubtThey tried to explain a thousand timesBut is never able to seem to findWhat will make them listen Instead of fight, So this poem is endingLet's all find an alternative from the sharp tools across our skinAnd hopefully you will noticeAll the beauty within. Memories within the Scars:We make permanent marks along our bodies with every bad memory hidden withinWe know that others do this as well, as they have sharp, and precise lines with memories within.We dont realize the beauty within us, nor do the others, they have problems much alike, and they dont know what to do.Except to drown in their sorrows, keeping the pain, anger, and sadness hidden underneath their thick hearts.We only sees ourselves as our own, we can trust nobody but ourselves.Life isnt easy, its a slide with many ups and downs, its a cakewalk full of challenges, and a cruel place where you need to work to survive, its a world of the fittest thrives.Even if it means to make permanent memories on their bodies, to remind them.But is it the best? Is it the best for them?Rivers and Roads:Life will have its current and life will have its road, let life take its course but know that you have to put effort into making you life, what you do is what makes you, but you can change anything within your life, you just need you put your mind to it, if you dont put effort you wont pass that steep hill, if you stay in that one spot of the slow current you wont go anywhere. So make your life, change it, shape it, dont let it control you.Pls don't feel bad about the people out there who are like this, life will go it's way and change for the matter.
