একটি সরল ছন্দিত তরঙ্গ গ্যাসের মধ্যে দিয়ে +x অক্ষের দিকে চলমান এবং ইহার বিস্তার 2 cm, বেগ 30 m/s এবং কম্পাঙ্ক 300 /sec । মূল বিন্দু হতে 100 cm দূরত্বে 6 sec পরে অগ্রগামী তরঙ্গটির সরণ কত ?

The answer is correct because the problem states that the wave travels at a speed of 30 m/s, and we need to determine the position of the wave after 6 seconds at a distance of 100 cm from the source.

First, calculate the distance the wave travels in 6 seconds:

    
• Distance = Speed × Time
    
• Distance = 30 m/s × 6 s = 180 m (or 18000 cm)

Next, we check if the wave has reached the point that is 100 cm away from the source:

    
• The wave travels 18000 cm, which is much greater than the 100 cm distance.

Since the question asks for the displacement of the wave at the 100 cm point, we need to determine if the wave reaches that point:

    
• After 6 seconds, the wave has passed the 100 cm location.
    
• At that position, a complete cycle of the wave may have reached, leading to a net displacement of 0 cm at that point because the wave oscillates around that point.)

Therefore, the displacement of the wave after 6 seconds at 100 cm distance from the source is indeed 0 cm.
