Q1. Consider the following: 1. Bluetooth device 2. Cordless phone 3. Microwave oven 4. Wi-Fi device Which of the above can operate between 2.4 and 2.5 GHz range of radio frequency band?
Explanation
The 2.4 GHz and 2.5 GHz ISM band (Industrial, Scientific, and Medical) is a part of the radio frequency spectrum commonly used for short-range communication technologies. This range is globally available for unlicensed use, making it ideal for a variety of wireless communication applications. Bluetooth devices, cordless phones, microwave ovens, Wi-Fi baby monitors, wireless cameras, and RFID systems operate in the 2.4 to 2.5 GHz range of the radio frequency band. While it allows a variety of devices to operate within it, managing interference is a key challenge in environments with multiple devices using the same frequency. This range is commonly used due to its balance between range and data capacity, making it suitable for short-range communication and other applications.

Q2. Recently, LASIK (Laser Assisted In Situ Keratomileusis) procedure is being made popular for vision correction. Which one of the following statements in this context is-not correct?
Explanation
LASIK is primarily used to treat refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. LASIK uses a laser to reshape the cornea, allowing light entering the eye to be properly focused onto the retina, improving vision. The goal of LASIK is to correct refractive errors and thereby reduce or eliminate the need for corrective eyewear like glasses or contact lenses. LASIK is typically not recommended for individuals under the age of 18 because their eyes may still be changing. Additionally, people over the age of 40 may not be ideal candidates due to presbyopia, a condition that affects near vision.
