The correct Answer is:
To determine which statement is false, let's analyze each statement one by one. ### Step 1: Analyze the First Statement **Statement 1:** "Photographic plate is sensitive for infrared rays." - Photographic plates are indeed sensitive to various wavelengths of light, including infrared rays. This statement is **true**. ### Step 2: Analyze the Second Statement **Statement 2:** "Infrared rays are visible." - Infrared rays are part of the electromagnetic spectrum but are not visible to the human eye. This statement is **false**. ### Step 3: Analyze the Third Statement **Statement 3:** "Ultraviolet rays are invisible." - Ultraviolet rays are also not visible to the human eye. This statement is **true**. ### Step 4: Analyze the Fourth Statement **Statement 4:** "As compared to visible light photons, infrared and violet have more energy." - This statement is incorrect. Violet light has more energy than infrared light. In the electromagnetic spectrum, the energy of photons increases from infrared to violet. Therefore, this statement is **false**. ### Conclusion The false statements are: - Statement 2: "Infrared rays are visible." - Statement 4: "As compared to visible light photons, infrared and violet have more energy." ### Final Answer The false statement is **Statement 2**: "Infrared rays are visible."

To determine which statement is false, let's analyze each statement one by one. ### Step 1: Analyze the First Statement **Statement 1:** "Photographic plate is sensitive for infrared rays." - Photographic plates are indeed sensitive to various wavelengths of light, including infrared rays.
