Question

1. choose the best answer.

frequency and wavelength are inversely related. this means that as wavelength increases, frequency
stays the same
decreases
increases

1. choose the best answers.

electromagnetic waves with __ energy have a __ wavelength.
less; longer
more; stronger
less; shorter
more; longer

1. choose the best answer.

Explanation:

1. For the first question, since frequency and wavelength are inversely related (using the formula \(c = \lambda f\) where \(c\) is the speed of light, \(\lambda\) is wavelength and \(f\) is frequency), when \(\lambda\) increases, \(f\) must decrease.
2. For the second question, using the formula \(E=h\frac{c}{\lambda}\) (where \(E\) is energy, \(h\) is Planck's constant, \(c\) is the speed of light and \(\lambda\) is wavelength), less energy (\(E\)) means longer wavelength (\(\lambda\)).

Answer:

1. B. decreases
2. A. less; longer
