Assessment

1. What does a thermal camera primarily detect? A. Infrared radiation associated with apparent temperature patterns B. Private passwords C. Radio traffic D. Payroll data

2. Why are thermal images different from visible-light photographs? A. They always identify objects exactly B. They represent infrared patterns rather than ordinary reflected visible light C. They eliminate interpretation D. They work exactly like normal photos

3. What is thermal contrast? A. A camera password B. A flight restriction C. The difference in apparent temperature between features or surfaces D. A file format

4. Why can reflections mislead thermal interpretation? A. Reflections never occur B. They guarantee the target is hot C. They replace context D. Some surfaces reflect thermal radiation from other objects or the environment

5. What does emissivity describe at a high level? A. How effectively a material emits thermal radiation B. A battery type C. A payroll rule D. A map projection

6. Why does time of day matter? A. Time never affects results B. Sun exposure and retained heat change surface temperatures and contrast C. Night guarantees perfect imagery D. Time replaces calibration

7. Which environmental factor can affect thermal collection? A. Marketing slogans B. Browser bookmarks C. Wind, rain, humidity, sunlight, material, or surface state D. Office furniture

8. Why start thermal collection with a mission objective? A. It guarantees perfect results B. It removes privacy duties C. It replaces safety D. It determines timing, distance, angle, coverage, sensor, and interpretation needs

9. What is a radiometric thermal sensor? A. A sensor that records temperature-measurement data within stated limits B. A standard visible camera C. A battery charger D. A payroll system

10. Why should analysts avoid overinterpreting thermal imagery? A. Colors prove every cause B. Patterns can have multiple causes and depend on environment, materials, geometry, and sensor limits C. Thermal imagery removes uncertainty D. One image explains everything

11. What is an anomaly in thermal inspection? A. Definite proof of failure B. A password reset C. A pattern that differs from expected background or comparable conditions and deserves review D. A flight-log format

12. Why may specialist review be needed? A. Thermal imagery is always self-explanatory B. Specialist review weakens evidence C. Review replaces documentation D. Consequential findings may require domain expertise for diagnosis and action

13. Why preserve original thermal files? A. They may contain radiometric data, metadata, settings, and context needed for review B. They should always be deleted C. Preservation removes privacy concerns D. Preservation guarantees conclusions

14. Why is privacy important? A. Thermal imagery is never sensitive B. It can reveal sensitive information about people, property, occupancy, or operations C. Privacy does not apply to sensors D. Privacy replaces safety

15. Which statement best summarizes thermal imaging? A. It reveals hidden truth automatically B. It removes human judgment C. It is a useful method for observing temperature patterns that requires planning, context, cautious interpretation, and responsible use D. Color alone proves exact causes
