Question

question 4
shorter wavelength =
lower
higher
question 5
which color would have a higher frequency?
green
orange

Explanation:

Step1: Recall the relationship between wavelength and frequency

The relationship between the speed of light ($c$), wavelength ($\lambda$) and frequency ($f$) is $c = \lambda f$. Since the speed of light in a vacuum is constant, wavelength and frequency are inversely - proportional. So, a shorter wavelength means a higher frequency.

Step2: Recall the order of colors in the visible spectrum by frequency

In the visible spectrum, the order of colors from lower to higher frequency is red, orange, yellow, green, blue, indigo, violet. So green has a higher frequency than orange.

Answer:

Question 4: Higher
Question 5: Green
