Science SOL 5.6-Light

Visible light is a form of ___________ energy, this can be SEEN 👁️and can ___________ in different ways when it contacts an ________📦

radiant, interact, object

What is radiant energy?

Energy that can OR cannot be seen by the human eye,👁️

What is another name for radiant energy?

Visible Light 💡

Visible light is a form of radiant energy. Can this be seen by the human eye or not?

Yes

What in our ecosystem produces a lot of radiant energy?

THE SUN! 😎🌞

Can we see the radiant energy from the sun?

No! It hurts!

What does light travel in? Does light need a medium/object in able to move?

Transverse waves, and NO light can travel on its own!

What does transverse mean?

move across , Like this emoji man runs across the road

How are light waves characterized?

By their wavelength

What is a wavelength?

The distance between any two MATCHING points on the waves that are next to each other.

Is the crest the tip of the wavelength or the drop?

TIP!

Is the trough the tip or bottom of the wavelength?

BOTTOM!

Can a wavelength be measured from any point on the wave?

Yes! It is measured to the same point on the next wave

What does it mean when "It is measured to the same point on the next wave" or what is the RULE to measuring wavelength, you start from _________ to ___________.

crest to crest OR
trough to trough

What is frequency?

The number of waves passing a given point in a designated time.

The more frequency the greater amount of _______________. So the less frequency would result in greater or less energy?

greater, less

How can we tell if the frequency is high?

When the crest to crest OR
trough to trough of a wavelength are CLOSE together.

What is the visible spectrum?

A range of colors that are determined by wavelength.

The colors of the visible spectrum are like the rainbow🌈. What are the colors of the visible spectrum?

Red, orange, yellow, green, blue and violet

What's an acronym to remember the colors of the visible spectrum?

ROYGBV🌈

What is the color of light that is produced when all the visible spectrum colors are mixed together?

White light!

Put the visible spectrum colors in order of longest to shortest wavelength.

red, orange, yellow, green, blue and violet

Put the visible spectrum colors in order from greater frequency to low frequency.

violet, blue, green, yellow, orange, and red

Light travel in ___________ paths. Until it hits an object, light would be r__________, re___________, t____________ and/or a_____________.

straight, reflected, refracted, transmitted, absorbed

What is an example of light being reflected?

When we see ourselves in the mirror

What is an example of light being refracted?

After it rains and we see a rainbow.

What is an example of light being transmitted or absorbed?

Light from outside is coming inside the room through the window.

Light can be ___________ when light bounces off an object. Like when light hits a mirror we see our ____________.

reflected, reflection

What does it mean to be transparent? Give 4 examples.

Light passes though easily. EX: clear glass, clear plastic wrap, water, air

What does it mean to be translucent? Give 4 examples.

Light passes through partially (not a lot) EX: wax paper, frosted glass, think fabrics, thin paper

What does it mean to be opaque? Give 3 examples.

Light does NOT pass through. EX: metal, wood, bricks

Light transfers __________ energy.

radiant

EX: Energy radiated from the sun☀️ is transferred to E_________ 🌍by l__________💡.

earth, light

When light is absorbed it w__________ 🔥Earth's land, air and water and facilitates plant growth through the process of p____________🌿.

warms, photosynthesis

Current technology like s___________ p__________, transform light energy from the sun into mechanical and electrical energy to produce enough e____________ power their house utilities and devices.

solar panels, electrical
