Question

question 14
the bending of light is refraction.
true
false
question 15
scientists can communicate with spacecraft in the outer reaches of the solar system because of the spectrograph.
true
false
question 16
in the spectrum of light, the light with the shortest wavelength is violet.
true
false

Explanation:

• Question 14: Refraction is defined as the bending of light when it passes from one medium to another. So the statement is correct.
• Question 15: Scientists communicate with spacecraft using radio - frequency communication, not a spectrograph which is used for analyzing light spectra. So the statement is false.
• Question 16: In the visible light spectrum, violet has a relatively short wavelength, but ultraviolet light has an even shorter wavelength. So the statement is false.

Answer:

Question 14: True
Question 15: False
Question 16: False
