Question

question 1
which color has the shorter wavelength?
red
purple
question 2
lower energy = ________ frequency
lower
higher
question 3
higher energy = ________ wavelength
longer
shorter

Explanation:

• For Question 1: In the visible - light spectrum, purple has a shorter wavelength than red.
• For Question 2: According to the energy - frequency relationship $E = h

u$ (where $E$ is energy, $h$ is Planck's constant, and $
u$ is frequency), lower energy corresponds to lower frequency.

• For Question 3: Using the relationship $E=\frac{hc}{\lambda}$ (where $c$ is the speed of light and $\lambda$ is wavelength), higher energy corresponds to a shorter wavelength.

Answer:

• Question 1: B. Purple
• Question 2: A. Lower
• Question 3: B. Shorter
