Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. She placed a ray box in front of a mirror. She changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light.

Which of the following is the dependent variable in this experiment?

a.) The mirror used to reflect the light
b.) The ray box used as the source of light
c.) Angle at which the light from the ray box strikes the mirror
d.) Angle at which the mirror reflects the light from the ray box

c.) Angle at which the light from the ray box strikes the mirror
d.) Angle at which the mirror reflects the light from the ray box

TheKaylaHope · Answer

The dependent variable is the variable that is being measured or observed in an experiment and is expected to change as a result of the independent variable. In this experiment, the dependent variable is the angle at which the mirror reflects the light from the ray box since this variable is being measured based on the changes made to the independent variable which is the angle at which the light from the ray box strikes the mirror. Therefore, the correct answer is option d.) the angle at which the mirror reflects the light from the ray box.
