Hello!
In Wave 3, there are 40 waves in the wave train. To find the Wavelength of the wave, you'll need to use a ruler to find the measure of the wave in centimeters (I can't really measure the wave because I would be measuring a picture and I wouldn't know if I was accurately measuring the wave), but I would estimate it to be about 2cm long. For the amplitude, I am not certain on what the amplitude would be. I could only manage to find the amount of wave sand the estimated length.
I hope this helps!

Answer:
Ray A = Incidence ray
Ray B = Reflected ray
Explanation:
From the law of reflection,
Normal: This is the line that makes an angle of 90° with the reflecting surface.
Ray A is the incidence ray: This is the ray that srikes the surface of a reflecting surface. The angle formed between the normal and the incidence ray is called the incidence angle
Ray B is the reflected ray: This is the ray leaves the surface of a reflecting surface. The angle formed between the reflected ray and the normal is called reflected angle
Answer:
C. The diameter of a wire
Explanation:
A micrometer screw gauge is a device used for the measurement of small dimensions which may not be measured accurately by the use of a vernier caliper, e.g diameter of a thin wire. it has a high degree of accuracy.
From the given option in the question, the measurement that can be made using a micrometer screw gauge is the diameter of a wire
The best way to look at it is the other way around.
Electromagnetic waves exist over a huge range of frequencies, from less
than 1 per second up to more than 3 billion billion billion per second.
If electromagnetic waves with frequencies between maybe about
4 million billion per second up to about 7.5 million billion per second
go into your eye, you SEE them.
Outside of that range, your eye doesn't know that there's anything there. But
IN that range, your eye has incredible nerve ends in the back that can tell the
difference between different frequencies. The highest frequencies in that range
produce the feeling of blue in your brain. The next highest ones make a feeling
of green. The next highest ones make the impression of yellow, and so on and
so on, down to the lowest frequencies that your eye can detect, and those look
red. If the frequency is any lower than red, you don't see it even when it pours
into your eyes.
