All of the various light
waves move with the same speed, a value
<span>abbreviated (c) equal to 3.00
× 108 m/s. The frequency ([1]) that light waves
pass a given point is</span>
measured in waves/second or
simply ‘per second’ (1/s).
the frequency of the wave f =
(3.00 × 10^8 m/s)/ 2.340 m
<span>f = 1.28x10^8 Hz</span>
A is the one so she could spot the differnece with natural and the unnatrual decline
Answer:
A feasible error could have been the removal of the sample before all water evaporated.
Explanation:
In order to determine the percentage of water in an hydrate, an experiment that could be performed is the heating of the sample until the mass does not change. If the student heated the sample an insufficient amount of time, water will be present in the sample, thus reducing the percentage reported.
