Intensity is independent of the wavelength/frequency.

I cannot answer that question without knowing their distances from us.
while Herschel is performing the experiment on prism he send a white light through a prism this white light is split in to seven colors violet, indigo, blue, green, yellow, orange, red. he observed that heat is increasing from violet to red. red color light has more heat than others. when he measured the beyond the red portion of light he observed more heat than the red light thus he named this invisible portion of light as infrared .where infra means after
The different hues are the result of different wavelength of light. The height of the waves define the brightness. Red is not brighter than violet, for example, unless the red light is stronger, peaking higher than the violet's peaks.
Since the moon does not have an atmosphere, the sunlight that reaches the surface of the moon is more intense than the sunlight that reaches the surface of the Earth after passing through the Earth's atmosphere.
The speed of violet light is slower than the red light in the prism.
violet because it has a higher frequency than red light
Here on earth it is violet wavelengths that scatter the most, however the earth's sun emits more blue light than violet so blue wavelengths are scattered more frequently than violet wavelengths.
Violet light has a higher frequency than red light by roughly a factor of 2.
Humans can see light all the way from red to violet, but not morethan red (infrared) nor more than violet (ultraviolet).
Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.
Violet because in the color spectrum it goes from weakest to strongest, starting from red all the way to violet, so violet penetrates the deepest. No it is red light. violet light in absorbed and/or reflected more than red light
Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter

The wavelength of violet light is shorter.
