Questions & Answers about Звук распространяется туда, куда вы его направляете.
Why do we use the pair туда, куда in this sentence instead of там, где?
We use туда, куда because both halves of the sentence involve direction or motion toward a destination. The verbs распространяется (propagates) and направляете (direct) answer the question of motion 'to where?', whereas там, где is used for static locations answering the question 'where at?'.
Why does the verb распространяется have the reflexive -ся ending here?
The -ся ending makes the verb intransitive, showing that the sound is spreading or propagating on its own. Without -ся, the verb распространять requires a direct object, meaning you would have to be actively spreading or distributing something else.
Is it grammatically acceptable to drop туда and just use куда?
In standard and written Russian, you need the full demonstrative-relative pair туда, куда to clearly link the main clause to the relative clause. While native speakers might sometimes drop туда in very casual or fast speech, keeping the matched pair is the standard rule and sounds much more natural.
Why is the accusative pronoun его used for an inanimate object like звук?
