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.
The primary process in making Cottage Cheese involves good dairy bacteria converting lactose to lactic acid. This lactose (or milk sugar) is an important component in our milk but unless it is converted by a good quality dairy bacteria, some off flavors or worse may result.
