What type of interference is illustrated at \( \mathrm{t}=1.35 \mathrm{~s} \) ?

To determine the type of interference occurring at \( t = 1.35 \, \text{s} \), we typically need more context, such as a graph of the wave interference over time or specific details about the wave sources (e.g., their frequencies, amplitudes, and phases). However, I can provide a general overview of the types of interference and how they might relate to a specific moment in time. ### Types of Interference 1. **Constructive Interference:** - **Description:** Occurs when two or more waves meet in phase, meaning their crests and troughs align. - **Result:** The amplitudes of the waves add up, resulting in a wave with greater amplitude. - **Example:** If two identical waves meet such that their peaks coincide, the resulting wave has double the amplitude. 2. **Destructive Interference:** - **Description:** Occurs when two or more waves meet out of phase, meaning the crest of one wave aligns with the trough of another. - **Result:** The amplitudes of the waves subtract from each other, which can result in reduced amplitude or complete cancellation. - **Example:** If two identical waves meet such that the peak of one coincides with the trough of another, they can cancel each other out completely. 3. **Dynamic Interference:** - **Description:** Involves changing interference patterns over time due to variations in the phase or amplitude of the interacting waves. - **Example:** Beats in sound waves where the interference pattern changes periodically, leading to alternating loud and soft sounds. ### Applying to \( t = 1.35 \, \text{s} \) Without specific details about the waveforms at \( t = 1.35 \, \text{s} \), it's challenging to definitively state whether the interference is constructive or destructive. However, if at this particular moment the wave peaks and troughs are aligned (in phase), **constructive interference** is occurring. Conversely, if the peaks of one wave align with the troughs of another (out of phase), **destructive interference** is taking place. **To provide a more accurate answer, please provide additional details such as:** - The nature of the waves involved (e.g., light, sound). - Amplitudes, frequencies, and phase relationships of the sources. - Any diagrams or graphs illustrating the interference pattern at \( t = 1.35 \, \text{s} \). With more information, a precise determination of the interference type at the specified time can be made.
