Question

question 3
which of these statements is accurate?
select one:
o a. scientists use instruments to detect invisible light energy waves.
o b. we see an apple as red because it absorbs red and reflects all other colors.
o c invisible light waves can be seen by the human eye.
o d. when colored light strikes a glass prism, the light leaves the prism as white light.

Explanation:

• Option A: Scientists do use instruments to detect invisible light energy waves (e.g., infrared cameras, UV sensors).
• Option B: An apple appears red because it reflects red light and absorbs other colors.
• Option C: Invisible light waves (like infrared, UV) cannot be seen by the human eye.
• Option D: When colored light strikes a glass prism, it is dispersed into its component colors (not leaving as white light if it was colored to start with).

Answer:

A. Scientists use instruments to detect invisible light energy waves.
