Quick 1,2,3: Light Waves

Why do green grapes look green?

• green grapes absorb green light

• green grapes transmit green light

• green grapes refract green light

• green grapes reflect green light

Ozone molecules or sulfuric acid droplets could prevent UV light from reaching the surface in some places on Earth. This might explain

• the same rate of frequency in skin cancer in Australia and Brazil

• the different rate of frequency in skin cancer in Australia and Brazil

• How wavelengths are formed for all colors in the color spectrum

• sunlight's movement

When a light wave hits a material:

• wavelengths disappear, sunlight transmits, or reflection doesn't exist off of a material

• light is absorbed, transmitted, or shows less frequency off of a material

• wavelengths disappear, light is absorbed, or is reflected off of a material

• light is absorbed, transmitted, or reflected off of a material

Carbon dioxide absorbs infrared light, so the infrared light can’t get out! What is the result?

• carbon poisoning

• greenhouse effect

• photosynthesis

• emission

A riddle for you. Guess my name correctly: I am a type of invisible light that is beyond violet on the spectrum.

• light source

• amplitude

• ultraviolet

• emit

A riddle for you. Guess my name correctly: An object that emits light.

• light

• light source

• energy

• transmit

Fill in the blanks in the correct order below. Melanin is a pigment or ________________ of the skin. Sunlight can cause damage to our genetic material called_______________.

• DNA ; coloring

• coloring ; DNA

• colorless appearance ; DNA

• DNA ; heredity

A Student Scientist like you supports and refutes claims. If Brazil and Australia receive approximately the same amount of sunlight, what might be a reason for the difference in skin cancer rate in the 2 countries?

• something the same about the UV light in the atmosphere

• something different about the UV light in the atmosphere

• the absence of UV light in the atmosphere

• none of the above
