- The answer is shorter wavelength and equal speed.
That is, compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have shorter wavelength and equal speed.
This can be seen by the reaction given below:

h= Planck's constant
c=speed of the light
=frquency
=wavelength
So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.
The answer is atom because it cannot be broken down into small substances

Answer:
pH = 4
Solution is acidic
Explanation:
Given data;
Hydronium ion concentration = 1 × 10⁻⁴ M
pH of solution = ?
Solution:
pH = -log [H₃O⁺]
pH = -log [ 1 × 10⁻⁴ ]
pH = 4
According to pH scale the pH 7 is neutral while the pH less than 7 is acidic and greater than 7 is basic. The given solution has pH 4 it means solution is acidic.
The answer is B. Enzymes.
Enzymes are biological catalysts that help cause reactions in your body.
