Yes, microwaves have less energy than visible light. The energy of electromagnetic waves, including microwaves and visible light, is directly related to their wavelength. The shorter the wavelength, the higher the energy, and vice versa.
Visible light consists of a range of wavelengths that our eyes can detect, roughly between 400 to 700 nanometers (nm). The colors we see correspond to different wavelengths within this range. Violet light has the shortest visible wavelength (around 400 nm), while red light has the longest visible wavelength (around 700 nm). Blue light, green light, yellow light, and orange light have wavelengths between violet and red.
Microwaves, on the other hand, have much longer wavelengths, typically ranging from about 1 millimeter (mm) to 1 meter (m). These longer wavelengths correspond to lower energy levels compared to visible light. As a result, microwaves have significantly less energy than visible light.
In the electromagnetic spectrum, microwaves fall between radio waves and infrared radiation. While microwaves are used for cooking in microwave ovens and for communication in technologies like Wi-Fi and cell phones, visible light is responsible for the colors we see, making it essential for our perception of the world around us.
