Is intensity adjustable?

Is intensity adjustable?

• A. No
• B. Not at all
• C. Only during calibration
• D. Yes

Answer: (D)

The key idea here is that intensity control means you can adjust how strong or bright the device’s output is. Being able to change intensity lets you tailor performance to the environment and your needs—for example, turning the output up when you need clearer visibility or stronger signaling, and dialing it down to reduce glare, discomfort, or risk of overexposure. Since the system provides a control to vary this setting, adjusting intensity is possible, making Yes the best choice. The other options imply no adjustment is possible or that adjustment is limited to a calibration phase, which wouldn’t reflect typical operation where users can fine-tune settings as needed.
