What causes the green color of grass?

• Grass functions as a prism, splitting light into different colors.

• Grass reflects red, orange, yellow, blue, indigo, and violet light, while absorbing green light.

• Green light is transmitted through the grass.

• Grass reflects green light to our eyes, and absorbs red, orange, yellow, blue, indigo and violet light.

When parallel rays of light hit an uneven surface, the uneven surface causes the angles of incidence to be unequal. This results in a blurry image. This is called:

• Absorption

• Transmission

• Refraction

• Diffuse reflection

Dentists can use this type of EM wave to identify cavities. Airports use this to scan luggage for dangerous substances and weapons.

• Gamma rays

• Ultraviolet radiation

• Infrared

• X-Rays
