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.
I've used cottage cheese and it makes the cake slightly more crumbly. To compact it you can add some fresh cream. Sour cream also makes a wonderful addition, and marries well with some lemon zest.p vote 3 down vote. ABSOLUTELY you can substitute cottage cheese (even fat free) for cream cheese in a cheesecake recipe. Small curd seems to work best--possibly because a bit more of the moisture is retained in the product after draining.
