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.
While most cheese hardly has a reputation as a diet food, cottage cheese has long been a staple in many health conscious diets. Available in several varieties -- low fat, low sodium or mixed with fruit -- cottage cheese is versatile in the kitchen and can be consumed on its own or added to sweet or savory recipes.
