Question

Fiona 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 light. she placed a ray box in front of a mirror. She changes 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 independent variable in this experiment?

Answer 1

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror (B)

Hope this helps <3

Answer 2

B. The angle at which the light from the ray box strikes the mirror.

What is independent variables?

The independent variables are those variables that always change in an experiment while control variables remain unchanged throughout the experiment.

Fiona changed the angle at which the light from the ray box strikes the mirror.

Thus, the independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.

The complete question is below:

( A The ray box used as the source of light)( B The direction along which the light moves) (C Angle at which the light from the ray box strikes the mirror) or (D Angle at which the mirror reflects the light from the ray box)
