Stuff that Inspires Poetry -or SIP for short

next: soundwaves can leave shadows, too


Q:
Why can only light waves cause shadow.Why cant sound waves cause shadows.
- Prudhvi Raj Borra (age 16)
Machilipatnam,Andhra,India
A:
In fact, shadows of sound waves exist. However in order to observe (hear) the effect the shadow casting object must be considerably larger than the wavelength of the sound.
Like light waves, sound waves can reflected, bent, refracted, diffracted and focused. Audible sound wavelengths are in the range of about 10 meters to about 2 centimeters, compared to less than one millionth of a meter for visible light.

DT's attitude to women is well covered by the lines from Lear:-

'Down from the waist they are centaurs, tho' women all above.
To the girdle do the gods inherit , beneath is all the fiends'

and it gets worse!
