Question

Bees which are not carrying honey , fly with a flapping frequency of 440 Hz while those which are carrying honey, fly with a flapping frequency of 300 Hz. The sound made by bees which are not carrying honey has
1 point
a long pitch
a higher pitch
a smaller loudness
a greater loudness

Answer 1

The honey bee which are not carrying honey will have a higher pitch.

Option b

Explanation:

• The pitch of the sound is dependent on the frequency of the oscillation of the sound wave. The frequency can be defined as the number of to and fro oscillation covered by the sound wave in one second. Higher the frequency higher is the pitch of the sound.
• this is with respect to the mass of the honey plus the honey fly.
• If they carry honey then their weight increases and hence the rate of vibration also decreases because the force will be more if they vibrate with the same frequency

Answer 2

The honey bee which is not carrying honey will have a higher pitch.

Option b

Explanation:

The pitch of the sound is dependent on the frequency of the oscillation of the sound wave. The frequency can be defined as the number of to and fro oscillation covered by the sound wave in one second. The higher the frequency higher is the pitch of the sound.

this is with respect to the mass of the honey plus the honey fly.

If they carry honey then their weight increases and hence the rate of vibration also decreases because the force will be more if they vibrate with the same frequency
