Of the following waves in the EM Spectrum (based on wavelength), (a)   would come BEFORE Visible Light (which allows us to see).

• infrared

• ultraviolet

• gamma

• x-rays

• visible light

A student drew a diagram shown to model an electromagnetic wave from the sun. Scientists have shown that ultraviolet light from the sun that has a wavelength of 315 to 400 nanometers can damage the retina. Use the drop-down menus to create the BEST question for the student to ask to determine whether the electromagnetic wave modeled will cause damage to the retina. What is the ​ (a)   distance between point ​ (b)   on the model?

• horizontal

• W and point Z

• vertical

• Y and point Z

• X and point Y

• W and point Y

Answer explanation

“Horizontal” is the correct response for the first drop-down menu because the wavelength is the horizontal

distance between the same relative locations on two successive wave oscillations. “W and point Z” is the

correct response for the second drop-down menu because these are the same relative locations, the peaks

on two successive wave oscillations.
