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.
Another main difference between the two types of cheese is that cottage cheese contains more amount of casein protein when compared to Cheddar cheese. This is virtually the reason why cottage cheese is preferred by bodybuilders and weightlifters. The amount fat in cottage cheese is low.
