# shorter wavelength higher energy

Question is : MCQ The higher energy level and shorter wavelengths are features of , Options is : 1. alpha radiation, 2. beta radiation, 3.infrared radiation, 4. ultraviolet radiation, 5. (2) b) Red light has a longer wavelength than blue light. (The “warming lamps” you see at restaurants emit infrared radiation. Visible light has higher energy than infrared light because visible light has higher frequencies. MCQ The higher energy level and shorter wavelengths are features of. This is a Most important question of gk exam. The higher frequency-higher energy results from Planck's realisation of the quantization of light and the resulting E=hf equation. 1 2 mv2 = hν − Φ ChemPrin3eT0129 This answer has been confirmed as correct and helpful. The wavelengths of visible light are: Violet: 380–450 nm (688–789 THz frequency) Blue: 450–495 nm; Green: 495–570 nm; Yellow: 570–590 nm; Orange: 590–620 nm; Red: 620–750 nm (400–484 THz frequency) Violet light has the shortest wavelength, which means it has the highest frequency and energy. 1. X-rays have shorter wavelengths (higher energy ) than UV waves and, generally, longer wavelengths (lower energy) than gamma rays. NULL. 0. a) Name the colors in visible light, in order of increasing energy (higher to shorter wavelength). None of these4.shorter its wavelength.correct5.lower Planck’s constant. Rays on the blue end of the spectrum have shorter wavelengths and more energy. The relationship between wavelength, frequency and energy means that: As the wavelength of an electromagnetic wave get shorter its frequency increases and as wavelength … The shorter the radiation's wavelength, the higher the radiation's energy -describes the relationship between the wavelength and strength of the Sun's radiation. The radio waves would have a lower energy and would travel slower than gamma rays. The number ofelectrons emittedmust be thesame because the intensities (photons/s) are the same. Sometimes X-rays are called Röntgen radiation, after Wilhelm Röntgen, who is usually credited as their discoverer. 3.0×10−14s−12.3.0×1014s−13.1.3×10−15s−14.120 s−15.7.5×1014s−1correctExplanation:00910.0pointsThe higher the frequency of light the1.higher the speed of light. Light waves with shorter wavelengths (and higher frequencies) also have more energy, so types of light like gamma rays, X-rays, and ultraviolet light are more energetic than visible light, and infrared, microwaves, and radio waves are less energetic than the light in the visible spectrum. will help. Higher frequency and shorter wavelengths are one and the same thing. Red has the longest wavelength, the shortest frequency, and the lowest energy. 450 nm light, which is higher in energy than the 500 nm light, will also emit electrons. To go back to the electromagnetic spectrum. The radio waves would have a shorter wavelength and higher energy than gamma rays. 2. lower its energy. Because X-rays have very high energy they are known as ionizing radiation and can harm living tissue. Frequency and energy are directionally proportional so the arrows in those two columns face in the same direction. However, the higher energy photons from the 450 nm light would yield electrons with a higher kinetic energy and therefore a higher velocity. Visible light has higher energy than infrared light because visible light has longer wavelengths. The anti-Stokes lines, with $\Delta J = -2$, arise from the emission of a photon with shorter wavelength (higher energy) than the incident photon. Explanation:01010.0pointsFrequency is1.the height of the wave. The specific selection rule is $\Delta J = \pm 2$. The electromagnetic rays just beyond the red end of the visible light spectrum are called infrared — they are warming but invisible. Log in for more information. 3. Orange light has a longer wavelength, a lower frequency, and a lower energy than blue light. X-rays have lower energy than gamma rays because X-rays have shorter wavelengths.
