Formative 9A: Electromagnetic Waves

Sam looks at the electromagnetic spectrum below. After evaluating the electromagnetic spectrum, Sam accurately noted that as the wavelength

• increases, the frequency remains constant.

• decreases, the frequency decreases.

• increases, the frequency increases.

• decreases, the frequency increases.
