Just like a bridge can have resonance and waves, an o neil cylinder would also have to contend with that.

Καθηγητά πως μπορούμε να τοποθετούμε σε κάποια κατασκευή, ενα δείγμα απο καθε υλικό και να εισπράττουμε την αντιστοιχία του σε ακουστική συχνότητα; θα με βοηθούσατε παρα πολυ στον πείραμα μου αυτό, αν είχατε τον χρόνο να ανταποκριθείτε. ευχαριστώ πολυ.

do force quantity have anythings to do with vibrating frequency of the objects? suppose i hit the object with 10 N force and later on with 50 N force, what will be the difference in frequency of vibration of the objects?

Αρχικα μπραβο σας τοσο για αυτο το βιντεο οσο και για τις οδηγιες μελετης που εχετε συμπεριλαβει στα τελευταια σας βιβλια, ειναι παρα πολυ χρησιμες. Χρησιμοποιησα τα βοηθηματα σας το 2012 για τις δικες μου εξετασεις και εχοντας μελετησει τα του 2020 εξεπλάγην με το ποσο τα βελτιωσατε.Ετσι οπως πατε θα τα κλεισετε τα φροντιστήρια:) Και εις ανώτερα.

Is glass can be broken by frequency of light just like frequency of sound??

@spockmx9426 3 жыл бұрын

Light waves and sound waves are two different things

@beeagle5801 3 жыл бұрын

@@spockmx9426 yeah they are different . But they r waves thus have frequency. But what kind of difference make them different .

@spockmx9426 3 жыл бұрын

@@beeagle5801 the frequency required to break the glass is about 556 hertz which can be produced through sound waves easily because it ranges only from 20 to 20000 hertz but the frequency of the electromagnetic spectrum ranges from 10^10 to 10^24 hertz which is very high from what frequency we actually need to break the glass and since the light waves can't have the frequency anywhere near 500 hertz it's not possible for the light waves to match the frequency of the particle's oscillating motion in the glass
