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.
Ricotta is a soft cheese that has a fine, moist, grainy texture. Cottage cheese is lumpier, whether the curds are small or large. Cream is added to the curds to create the rich creamed cottage cheese we are all familiar with. For low-fat cottage cheese, 1% or 2% milk replaces the cream. A half cup of creamed cottage cheese contains about 115 calories, while 1% cottage cheese has about 80 calories.
