    Yang membedakan antara gelombang tranversal dan gelombang longitudinal adalah….

    • Frequency

    • Amplitudo

    • Panjang gelombang

    • Arah getarnya

    Correct Answer
    A. Arah getarnya
    Explanation
    The difference between transverse waves and longitudinal waves lies in the direction of vibration. In transverse waves, the particles vibrate perpendicular to the direction of wave propagation, while in longitudinal waves, the particles vibrate parallel to the direction of wave propagation. Therefore, the correct answer is "Arah getarnya" which translates to "the direction of vibration."

    Beberapa hewan keluar pada malam hari, termasuk salah satunya adalah kelelawar. Kelelawar dapat terbang tidak menabrak benda di malam hari. System apa yang digunakan untuk membantu kelelawar dapat terbang di malam hari adalah system sonar. Termasuk apakah system sonar tersebut?

    • Gelombang

    • Energi

    • Gelombang Longitudinal

    • Gelombang Transversal

    Correct Answer
    A. Gelombang Longitudinal
    Explanation
    The correct answer is "Gelombang Longitudinal". Gelombang longitudinal adalah jenis gelombang yang merambat dengan arah getaran yang sejajar dengan arah perambatannya. Gelombang suara adalah contoh gelombang longitudinal. Dalam konteks ini, kelelawar menggunakan sistem sonar yang menggunakan gelombang suara untuk membantu mereka terbang di malam hari tanpa menabrak benda-benda di sekitarnya.

    I.     Gelombang longitudinalII.    Gelombang tranversalIII.   UltrasonikIV.  InfrasonikPernyataan diatas yang sesuai dengan penerapan sistem sonar pada kelelawar adalah….

    • Gelombang Longitudinal

    • Gelombang transversal

    • Ultrasonik

    • Infrasonik

    Correct Answer(s)
    A. Gelombang Longitudinal
    A. Ultrasonik
    Explanation
    The correct answer is Gelombang Longitudinal and Ultrasonik. Gelombang longitudinal adalah gelombang yang merambat dalam arah yang sejajar dengan getaran partikel mediumnya. Pada sistem sonar kelelawar, gelombang suara yang dipancarkan oleh kelelawar adalah gelombang longitudinal yang merambat melalui medium udara. Ultrasonik adalah gelombang suara dengan frekuensi di atas batas pendengaran manusia, yang digunakan oleh kelelawar untuk berkomunikasi dan mendeteksi mangsanya. Oleh karena itu, jawaban yang benar adalah Gelombang Longitudinal dan Ultrasonik.

    Ciri-ciri gelombang apa yang digunakan pada system sonar Pak Anton?

    • Pemantulan

    • Perambantan melalui media

    • Difraksi

    • Interferensi

    • Berbalik arah

    Correct Answer(s)
    A. Pemantulan
    A. Perambantan melalui media
    A. Berbalik arah
    Explanation
    The correct answer options for this question are "Pemantulan, Perambantan melalui media, berbalik arah." These characteristics are associated with the use of waves in sonar systems. Pemantulan refers to the reflection of waves off surfaces, which is important in sonar for detecting objects underwater. Perambantan melalui media refers to the propagation of waves through a medium, which is how sonar waves travel through water. Berbalik arah means the waves change direction, which is necessary for sonar to detect objects in different directions. These characteristics are crucial for the functioning of sonar systems in detecting and locating underwater objects.

    Sudah hampir tiga tahun daerah Klampok mengalami kekeringan. Bahkan danau terbesar di daerah tersebut sedikit menyisakan air. Suatu hari hujan besar turun didaerah tersebut selama 1 bulan lamanya. Pak Anton sebagai ahli geosains ingin mengukur banyaknya air yang tertampung dalam danau tersebut selama hujan. Kemudian pak Anoton membeli system sonar untuk mengukur kedalaman danau tersebut. Setelah dilakukan percobaan hasilnya gelombang yang dipancarkan kembali setelah 2 detik. Kecepatan yang diatur Pak Anton yakni 180 km/jam.________

    Correct Answer(s)
    50 meter
    Explanation
    During the experiment, Pak Anton used a sonar system to measure the depth of the lake. The sonar system emits a wave and measures the time it takes for the wave to bounce back, which can then be used to calculate the depth of the lake. In this case, the wave took 2 seconds to bounce back. Since the speed of sound in water is approximately 1500 meters per second, we can calculate the depth of the lake by multiplying the speed of sound by the time it took for the wave to bounce back. Therefore, the depth of the lake is 1500 meters per second times 2 seconds, which equals 3000 meters or 3 kilometers. However, since the answer given is in meters, we convert 3 kilometers to meters, which is 3000 meters.

    Anton ingin membuktikan teori mengenai bunyi dapat digunakan untuk mmengukur suatu kedalaman. Suatu hari anton ikut ayahnya. Ayah anton adalah seorang montir PAM sumur. Setelah menyiapkan alat utnuk mengukur kedalaman sumur, didapatkan hasil bahwa gelombang yang diterima alat setelah 0.5 detik. Jika kecepatan gelombang yang digunakan yakni 500 m/s. Berapakah kedalaman sumur yang akan diperbaiki ayahnya Anton?________

    Correct Answer(s)
    12.5 meter
    Explanation
    Based on the information given, Anton wants to prove that sound can be used to measure depth. He accompanies his father, who is a well mechanic. They prepare a device to measure the depth of the well, and they find that the device receives a wave after 0.5 seconds. Knowing that the speed of the wave is 500 m/s, we can calculate the depth of the well using the formula distance = speed × time. Therefore, the depth of the well that Anton's father will fix is 12.5 meters.
