The distance that is not a wavelength in the image is C to E.
<h3>What is wavelength?</h3>Wavelength is the distance between two successive crests or two successive trough or crest to trough.
It is also the distance over which the wave's shape repeats.
Based on the image, the following are wavelengths;
- A to E, this is wavelength because it is between a crest and a trough.
- B to F, this is wavelength because it is between two successive crest.
- D to H, this is wavelength because it is between two successive trough.
Thus, the distance that is not a wavelength in the image is C to E.

The average speed between 0 h and 2.340 h is 6.97 Km/h
Average speed is defined as the total distance travelled divided by the total time taken to cover the distance.
With the above formula, we can obtain the average speed between 0 h and 2.340 h as illustrated below:
- Total time = 2.340 – 0 = 2.340 h
- Total distance = 16.3 – 0 = 16.3 Km
- Average speed =?

Answer:
The speed of electron is
Explanation:
Given that,
Separation of the plate = 1.20 cm
Suppose the field is .
If the electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate.
What the speed does it leave the hole?
We need to calculate the acceleration
Using formula of electric force
We need to calculate the speed of electron
Using equation of motion
Put the value of acceleration in the formula
Put the value into the formula
Hence, The speed of electron is
