One is shortwave radiation or short wavelength radiation and the other is longwave radiation/long wavelength radiation. The diagram below shows the range of shortwave radiations. There is no proper definition of shortwave radiations as there is no standard cut off for near infrared radiations range.
Cottage cheese is a fresh cheese curd product with a mild flavor. It is drained, but not pressed, so some whey remains and the individual curds remain loose.
1 If cottage cheese develops an off odor, flavor or appearance, it should be discarded for quality purposes; if mold appears, discard the entire package.  Only uncreamed (dry) cottage cheese should be frozen; creamed cottage cheese will become too mushy after freezing.
