We need UV from theSunto charge the ionosphere.

... so .,sun spots are cooler ... so darker .. so wave lenght is
lower .. so give out more uv than normal

that sound right ?

Sounds right to me.

Not quite right. UV is a higher frequency than visible light and X-ray
are a higher frequency than UV.

Low to high frequency is infra red (radiated heat), visible light, UV,
X-rays.


I use good old "Roy G. Biv"* to remember it. (For those unfamiliar
with this mnemonic, "vide infra," -- pun intended.) So, we get...

infrared ("below" red) -- red (the "R" in Roy) -- other colors, in
order -- violet (the "V" in Biv) -- ultraviolet ("beyond" violet).

A little Latin and etymology goes a long way.

[* Roy G Biv == the order: Red, Orange, Yellow, Green, Blue, Indigo,
Violet.]

Which is also mostly follows the resistor color code.

0 black
1 brown
2 red
3 orange
4 yellow
5 green
6 blue
7 indigo (purple)
8 gray
9 white


When, as a wee lad, I first tackled trig., my dissolute uncle taught
me a wonderfully effective mnemonic for the sin, cos, and tan
relationships.

Since it is somewhat vulgar, I will refrain from repeating in here, as
I have seen complaints of a prudish nature about certain posts.
(Although I did not see the original "offensive" posts.)

Suffice it to say it concerned practitioners of the world's oldest
profession and the wares they had on offer.

I was taught it once and it has never once failed me.
