What is the temperature of a star whose maximum light is emitted at a wavelength of 800 nm?
To find the temperature of a star based on the wavelength of maximum light emission, we can use Wien's displacement law, which states that the wavelength of maximum emission (( \lambda_{max} )) is inversely proportional to the temperature (T) in Kelvin. The formula is ( T = \frac{b}{\lambda_{max}} ), where ( b ) is Wien's displacement constant, approximately ( 2.898 \times 10^{-3} , \text{m} \cdot \text{K} ). For a wavelength of 800 nm (or ( 800 \times 10^{-9} ) m), the temperature is roughly ( T \approx \frac{2.898 \times 10^{-3}}{800 \times 10^{-9}} \approx 3622.5 , \text{K} ). Thus, the star has a temperature of about 3623 K.
What wavelength of maximum intensity does the Sun emit?
The Sun emits light in a broad range of wavelengths, peaking in the visible spectrum around 500 nanometers, which is green light. This peak intensity is a result of the Sun's temperature, which determines its blackbody radiation curve.
What is the temperature of a star whose maximum light is entitled at a wavelength of 290nm?
The temperature of a star can be calculated using Wien's law. Given the peak wavelength of 290nm, we can use the formula λmax = b/T, where b is a constant (2.898 x 10^-3 m K) to find the temperature of the star. In this case, the temperature would be approximately 10,000 K.
How do astronomers determine the temperature of stars?
Astronomers determine the temperature of stars by analyzing the colors of light they emit. This is done using a tool called a spectrometer, which breaks down the light into its different wavelengths. By studying the distribution of these wavelengths, astronomers can calculate the temperature of a star.
Can light microscopes magnify up to 1000000 times?
No, light microscopes typically cannot magnify specimens up to 1,000,000 times. Most light microscopes have a maximum magnification of around 1,000 to 2,000 times, limited by the wavelength of light. For higher magnifications, electron microscopes are used, which can achieve magnifications of up to 1,000,000 times or more due to their use of electron beams instead of light.
What is the sun's wavelength of maximum energy emission in what range?
The Sun's wavelength of maximum energy emission falls within the visible light spectrum, specifically in the range of around 500 to 600 nanometers. This corresponds to the green to yellow part of the spectrum.
What is maximum wavelength of absorbance of potassium permanganate?
The maximum wavelength of absorbance for potassium permanganate is around 525 nanometers. At this wavelength, potassium permanganate exhibits a strong absorption peak due to its characteristic deep purple color. This absorption peak is often used in spectrophotometric analyses to quantify the concentration of potassium permanganate in solution.
What is maximum wavelength of absorbance of sodium dichromate?
The maximum wavelength of absorbance for sodium dichromate typically occurs around 350-370 nanometers (nm). This absorbance is primarily due to the presence of the chromate ion, which exhibits strong UV-visible absorbance characteristics. The specific wavelength can vary slightly depending on the concentration and the solvent used.
What is resonance wavelength?
Resonance wavelength refers to the specific wavelength at which a material or system exhibits maximum absorption or emission of light. This wavelength is determined by the material's properties such as refractive index and the physical dimensions of the system. Resonance wavelength is important in various fields, including optics, photonics, and spectroscopy.
20000 K What is the wavelength at which it radiates most strongly?
To find the wavelength at which an object radiates most strongly, you can use Wien's Law, which states that the wavelength of maximum intensity radiation (λmax) is inversely proportional to the temperature (T). In this case, for 20,000 K, the wavelength would be around 144.44 nanometers (nm).
What is the maximum wavelength at which electromagnetic radiation can occur?
The maximum wavelength at which electromagnetic radiation can occur is infinite.
Why is red light having maximum wavelength?
Because red light has minimum frequency and thus it has maximum wavelength.
What is the temperature of a star whose maximum light is emitted at a wavelength of 800 nm?
To find the temperature of a star based on the wavelength of maximum light emission, we can use Wien's displacement law, which states that the wavelength of maximum emission (( \lambda_{max} )) is inversely proportional to the temperature (T) in Kelvin. The formula is ( T = \frac{b}{\lambda_{max}} ), where ( b ) is Wien's displacement constant, approximately ( 2.898 \times 10^{-3} , \text{m} \cdot \text{K} ). For a wavelength of 800 nm (or ( 800 \times 10^{-9} ) m), the temperature is roughly ( T \approx \frac{2.898 \times 10^{-3}}{800 \times 10^{-9}} \approx 3622.5 , \text{K} ). Thus, the star has a temperature of about 3623 K.
Is any wavelength maximum is universal?
No.
What is maximum wavelength in the spectrum?
The wavelength is the spatial period of the wave and it can be measured between any 2 points with the same phase. The maximum wavelength in the spectrum is 502 nm.
Using planck's law determine the wavelength of maximum emission intensity for blackbody with a temperature of 6000K?
The wavelength of maximum emission intensity can be found using Wien's displacement law, which states that λ_max * T = 2.898 x 10^-3 m*K. Plugging in the temperature of 6000K, we get λ_max = 2.898 x 10^-3 / 6000 = 4.83 x 10^-7 meters or 483 nm.
What is maximum wavelength for cibacron Yellow FN2R dye?
The maximum wavelength for cibacron Yellow FN2R dye is typically around 420-430 nm.
