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.
Cottage cheese is prepared by boiling and curdling milk with the help of acidic substances such as lime or vinegar. As the milk boils, it starts to curdle, forming lumps of curds. These curds are then pressed to squeeze out the whey or milk serum to form a big lump of curd or cheese.
