An older musician's lenses have become stiffer with age. The position of the music stand can be adjusted.
Which statement explains how changing the position of the music stand could make the notes easier to focus?
Moving the stand farther away means the light is more spread out when it reaches the eyes, so the lenses need to refract it more strongly.
Moving the stand closer means the light is more spread out when it reaches the eyes, so the lenses need to refract it less strongly.
