Question

Bees on their way to collect honey have higher pitch as compared to the bees returning back to their hives. Why?​

Answer 1

$\boxed{{\bold\red{\frak{❥Answer★}}}}$

No, honey bees do not leave and return. If they are gone, they're not coming back. They may have absconded, meaning they abandoned their hive and selected another location to live, or the colony may have died out for one reason or another. ... If you want to continue keeping bees, you need to acquire a new colony.

Answer 2

Answer:

Pitch means number of oscillations taken per second, which is called frequency.

When bees are heavy, they took less oscillations and when are lighter , they took more oscillations.
