The correct Answer is:
To analyze the given statements, we will break down the concepts of diffraction, wavelength, and their implications on sound and light. ### Step 1: Understand the Statements - **Statement I**: We can hear around corners, but we cannot see around corners. - **Statement II**: The wavelength of sound is much greater than the wavelength of light. ### Step 2: Define Diffraction Diffraction is the bending of waves around obstacles or through openings. The extent of diffraction depends on the relationship between the wavelength of the wave and the size of the obstacle. ### Step 3: Compare Wavelengths - The wavelength of sound waves is typically in the range of meters (e.g., 1 meter to several meters). - The wavelength of light waves is in the range of nanometers (e.g., 400 nm to 700 nm). ### Step 4: Analyze Statement I - Since the wavelength of sound is much larger than typical obstacles (like corners), sound waves can bend around these obstacles, allowing us to hear sounds from around corners. - In contrast, the wavelength of light is much smaller than the size of typical obstacles (like walls or corners), which means light does not diffract significantly around these obstacles, preventing us from seeing around corners. ### Step 5: Analyze Statement II - This statement is true as the wavelength of sound is indeed much greater than the wavelength of light. This difference in wavelength is crucial for understanding why we can hear around corners but cannot see around them. ### Step 6: Conclusion Both statements are true, and Statement II provides a correct explanation for Statement I. Therefore, the relationship between the wavelengths of sound and light explains the phenomenon described in Statement I. ### Final Answer: Both statements are true, and Statement II is the correct explanation for Statement I. ---
