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.
In summary, cottage and ricotta cheeses differ in the following aspects: 1. Cottage cheese is made from the curd byproduct, whereas ricotta is made from the whey byproduct of cheese production. 2. Ricotta cheese is said to have a lighter texture when compared to cottage cheese. 3. Cottage cheese is said to be lumpier than ricotta cheese.
