The wavelength of a wave refers to the horizontal distance that is travelled by a wave.
<h3>What is wavelength?</h3>
The wavelength of a wave is given by the formula;
v =λf
f = v/λ
Substituting the values;
f = 3 * 10^8 m/s/410 * 10^-9 m
f = 7.3 * 10^14 Hz
for 2
f = 3 * 10^8 m/s/434 * 10^-9 m
f = 6.9 * 10^14 Hz
for 3
f = 3 * 10^8 m/s/486 * 10^-9 m
f = 6.2 * 10^14 Hz
for 4
f = 3 * 10^8 m/s/657 * 10^-9 m
f = 4.6 * 10^14 Hz

Answer:
1. Uniform, non visible
2. Visible, non uniform
3. Uniform, non visible
4. Visible, non uniform
5. Visible, non uniform
Explanation:
A heterogeneous mixture is simply any mixture that is not uniform in composition — it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogenous mixture
visible state of matter is when you can easily difference two components of a mixture
non visible is when the state of the matter in the substance is not visible to the eye, it can't be differentiated
Answer:
False
Explanation:
The urine is produced in the kidneys, each one of the kidneys is connected to a ureter. The ureter is a tube that propels the excreted urine to the urinary bladder. The urinary bladder is a deposit for the urine, here is collected and stored before disposal. After the urinary bladder, the urine goes through the urethra, which is a tube, to exit the body.
