Physical Science Unit Waves

Which letter represents amplitude?

• A
• B
• C
• D

Why is the sky blue?

• because the atmosphere absorbs blue light and reflects the other colors
• because nitrogen and oxygen scatter blue more than the other colors
• because the ocean reflects its blue color to the sky
• because nitrogen and oxygen molecules scatter red and oranges away during the sunrise leaving blue for the day time
