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.
Blue cheese is made with Penicillium roqueforti mold spores. These molds help create the cheese. However, different types of mold can grow on the cheese after you purchase it. Cut off exterior mold that grows on the cheese after you purchase it and keep cheese refrigerated. The new molds that grow on the cheese are not necessarily the same molds used to produce the product.
