2023 Waves Unit Review

Scientists have shown that ultraviolet light from the sun that has a wavelength of 315 to 400 nanometers can damage the retina. Choose the BEST question for the student to ask to determine whether the electromagnetic wave modeled will cause damage to the retina.

• What is the vertical distance between point X and point Z?
• What is the vertical distance between point X and point Y?
• What is the horizontal distance between point W and point Z?
• What is the horizontal distance between point W and point Y?
