In the explanation of Doppler Effect using the sound waves, what happens to the waves that are emitted in the opposite direction the object is moving?

nucleus

would be most reasonable answer tbh

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
