Who discovered the relationships between stars temperature and the brightness?
Ejnar Hertzsprung and Henry Norris Russell,working independently, realized the relationship between a star's temperature and its brightness.Together, in 1910, they formed what is now known as the Hertzsprung--Russell diagram or HR Diagram.It's a scatter graph showing the relationship between a star's absolute magnitudes, their spectral types and temperatures.
What type of relationship exists in main sequence stars temperature and brightness?
In main sequence stars, there is a direct relationship between temperature and brightness, known as the Hertzsprung-Russell diagram correlation. Generally, hotter stars emit more light and are thus more luminous. This relationship is due to the physics of stellar fusion, where increased temperature leads to higher energy output. As a result, main sequence stars that are larger and hotter tend to be brighter than their cooler, smaller counterparts.
Who was the first to classify stars by their brightness?
The first to classify stars by their brightness was the Greek astronomer Hipparchus in the 2nd century BC. He ranked stars based on their apparent magnitude, with 1 being the brightest and 6 being the faintest.
How is the brightness of a Cepheid star calculated by knowing the period?
The brightness of a Cepheid star is determined by its period-luminosity relationship, which is a relationship between the star's variability period and its intrinsic luminosity. By measuring the period of a Cepheid star, astronomers can use the period-luminosity relationship to calculate its luminosity, and from there determine its apparent brightness as observed from Earth.
What is the relationship between temperature and relative humidity.?
The temperature determines the humidity.
Who discovered the relationship between the star temperature and brightness?
Hertzsprung and Russell.
Who discovered the relationship between a star brightness and temperature?

Who Discovered The Relationship Between The Stars Temperatures?
The relationship between a star's temperature and brightness was discovered independently around 1910 by Ejnar Hertzsprung and Henry Norris Russell. The relationship between these to parameters is depicted in a Hertzsprung-Russell diagram or H-R diagram.
IN main sequence stars what is the relationship between brightness and temperature?
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
What is the relationship between brightness and temperature shown within the main sequence?
As temperature increases the absolute brightness increases

What is the relationship between wavelength and hue, and how does it compare to the relationship between brightness and which other attribute?
The relationship between wavelength and hue is that shorter wavelengths correspond to cooler colors like blue and longer wavelengths correspond to warmer colors like red. This relationship is similar to the relationship between brightness and intensity, where higher brightness levels correspond to higher intensity levels.
What is the Relationship Between Voltage And Brightness of the Bulb?
The relationship between voltage and brightness of a bulb is directly proportional. As voltage increases, the brightness of the bulb increases because higher voltage provides more energy for the bulb to emit light. Conversely, decreasing voltage reduces the brightness of the bulb.
What does the HR diagram depict?
The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
