Which feature of a wave determines its color in the visible spectrum?
a. amplitude
b. composition
c. temperature
d. wavelength

(D). The wave length of a wave determines the color in the visible spectrum.

Explanation:

We know that,

The electromagnetic spectrum define the range of the electromagnetic radiation and the wavelength of all lights.

The wave length of the visible light is from 380 nm to 750 nm.

Violet light has the shorter wavelength and red light has the longest wavelength.

The wave length for Violet light is 380 nm to 450 nm.

The wave length for blue light is 450 nm to 495 nm.

The wave length for green light is 495 nm to 570 nm.

The wave length for yellow light is 380 nm to 450 nm.

The wave length for orange light is 590 nm to 620 nm.

The wave length for red light is 620 nm to 750 nm.

Hence, The wave length of a wave determines the color in the visible spectrum.

The correct answer is

D.wavelength

In fact, the colour of visible light depends on the wavelength of the wave. The visible light spectrum goes approximately from wavelength of 380 nm (corresponding to violet light) to 750 nm (corresponding to red light), and the different colours in between correspond to different wavelengths. For instance, blue light has wavelength of 450-500 nm, while yellow light has wavelength of 570-590 nm.

the answer is false

explanation:

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
