A secondary rainbow is dimmer because the light is being dispersed and reflected twice within a raindrop. Extra reflection accounts for a dimmer and less frequently observed secondary bow. Extra reflection results in a 50 degree angle for the dispersion of the color red and a reverse in order of the colors.

Is secondary pollutants more harmful than primary pollutants?
Primary air pollutants are emitted directly into atmosphere from a process such as exhaust from a engine, industries, volcanic eruption Secondary air pollution are formed in the air when primary pollutants interact.
What is primary pollution?
Pollution is any foreign substance present in more concentration than safer limits. They are two types of pollutants 1. Primary pollutants 2. Secondary pollutants Primary pollutants are those which generated directly from Source . That type of pollution is generally termed as primary pollution. Ex : Carbondioxide , Sulphur dioxide etc in case of Air pollution Secondary pollutants are those which formed by the combination of more than two or more primary pollutants Ex : Ozone , Photo chemical smog in case of air pollution
Are primary seismic waves slower than secondary waves?
Primary waves are called so because they are the first to arrive, and secondary waves are called so because they arrive second. Based on this logic I would say no. There is in fact a marked difference, which is used to tell how far away the epicenter is from a particular seismograph.
What are the energy levels in an energy pyramid?
energy than secondary, than primary, than chief
Is the secondary storage faster than main memory?
No. The secondary storage is typically slowerthan primary storage. But the secondary storage has higher capacity than primary storage.
What are the functions of primary and secondary groups?
A primary group has fact to face interactions and is more intimate than secondary groups. Secondary groups are more formal.
What color is the rainbow a primary color or a secondary?
Primary colors are the three basic colors red yellow and blue. Secondary colors are created when primary colors are mixed for example: green (blue yellow) purple (red blue) orange (red yellow)
Does a step-up transformer have fewer turns of wire in the primary than in the secondary?
Yes, a step-up transformer has fewer turns of wire in the primary than in the secondary.
What is primary and secondary constriction in chromosomes?
centromere is the primary constriction and constriction other than primary constriction is called secondary constriction. it is useful in the recognition of a chromosome from the set.
A transformer has 150 turns on the primary coil and is connected to a 120 volt power source How many turns will be needed on the secondary coil to provide a secondary voltage of 40 volts?
600 volts I'd like to point out that your question is asking for the secondary voltage, which is usually lower than the primary, where there are more windings on the secondary than primary - Thus your secondary is higher voltage than your primary. I would say the question should be worded differently so the primary has 500 windings, and the secondary has 100 windings.
Is cherry primary or secondary source?
Its a primary source as it comes off a tree - cant get more primary than that
How can primary research be less costly than secondary?
yes
Do primary colors fade more than secondary colors?
yes.. they do
What are disadvantages of primary sources of information?
Is costlier than secondary information.
When a secondary insurance allows more than primary allowed can you keep overpayment?
If I'm not mistaken, and I could be wrong, when the secondary insurance allowes more than the primary, the primary contractual adjustment is voided and the contractual obligation of the secondary should be applied. This will cause the balance to be zero when the adjustment of the secondary is the reflecting contractual obligation. That is how I was taught and it does make sense.
