Final answer:
Simultaneous oral reading improves students' accuracy levels. The phenomenon of superposition does not depend on the waves having the same frequency.
Step-by-step explanation:
The statement that simultaneous oral reading improves students' accuracy levels is true. When students read orally together with their peers or with the teacher, it helps them improve their pronunciation, fluency, and comprehension. By listening to each other read, students can model correct reading strategies and identify and correct their own mistakes. This active and collaborative reading practice can lead to improved accuracy levels in reading.
As for the ability of waves to superimpose if their frequencies are different, this is true. The phenomenon of superposition does not depend on the waves having the same frequency. Different frequency waves can and do superimpose when they intersect, creating complex patterns of interference which is the basis for phenomena such as beats in acoustics.
