1. Without light we can't see things around us.

2. Red has the longest wavelength, Violet has shortest wavelength.

3. Rainbows are made from water droplets.

4. In Earth, most important light is the sun.

5. We can't see X-Rays, Radio waves, microwaves and Gamma Rays.

6. We can see Visible lights.

The colour spectrum
Light travels in waves. You can see  Visible lights but you cannot see light like microwaves and radio waves

# data[].attributes.body
The colour spectrum is a spectrum that has many colours. The lowest ray is violet and highest is red.
光譜是具有多種顏色的光譜。 最低的射線是紫色，最高的射線是紅色。

# data[].attributes.body
The lowest ray is the violist one and the highest ray is the red one.

# data[].attributes.body
The shortest wave length is violet and longest is red. There are gamma rays, micro waves, x rays, etc.

Extra : there are also alpha rays and beta rays. alpha ray can't pass paper, beta rays can pass paper but stop at metals, gamma rays burn paper, metal but thick lead shielding will stop it.

light has visible and invisible light waves ,it has radio waves,microwaves ,x-rays,and gumma rays .electromagnetic radiation is the energy of light.
光有可見和不可見的光譜,它的能量叫電磁波.

Infared light is red and ultraviolet light is blue

the lowest ray is the microwave
the rainbow 🌈 is always the same order
black absorbs colour and white shows the light
if you shine light into a pirimid it turns into a rainbow

colour spectrum is a thing that you can see some of it and some you can‘t see.Also, they all have colourwaves

# data[].attributes.body
Color spectrum is:

# data[].attributes.body
There are different types of radiation for example: electromagnetic radiation, radio waves, micro waves, x-rays, and gamma rays. They are all called the electromagnetic spectrum and they all have different wave lengths. Radio and the color red has the longest wave and gamma and purple waves has the shortest wave. The color white reflects all colors and the color black absorbs all color.
