The wavelength of radio waves is much longer than the wavelength of visible light waves

Explanation:

Electromagnetic waves are periodic oscillations of the electric and the magnetic fields, occuring in a plane perpendicular to the direction of motion the wave.

Electromagnetic waves are the only waves able to travel in a vacuum; they travel at the speed of light:

c=3.0\cdot 10^8 m/s

Electromagnetic waves are also classified into 7 different types, according to their wavelength/frequency. From longest to shortest wavelength, we have: (with the corresponding wavelength written in the brackets):

Radio waves (>1 m)

Microwaves (1 mm - 1 m)

Infrared (750 nm - 1 mm)

Visible light (380 nm - 750 nm)

Ultraviolet (10 nm - 380 nm)

X-rays (0.01 nm - 10 nm)

Gamma rays (<0.01 nm)

So from the table, we can see that:

The wavelength of radio waves is much longer than the wavelength of visible light waves.

Light is less energetic than X-rays.

Explanation:

The electromagnetic spectrum refers to the range of wavelengths or frequencies over which electromagnetic radiation extends. It is the entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light. In the electromagnetic spectrum, the entire distribution of electromagnetic radiation is done according to their frequency or wavelength.

The energy of an electromagnetic wave depends on its frequency and wavelength. The shorter the wavelength, the greater the energy of the electromagnetic wave but the larger frequency, the greater the energy of the electromagnetic wave.

X-rays has a frequency of about 1×10^20 Hz compared to visible light of frequency of about 1×10^15 Hz. Hence X-rays, having a larger frequency, is more energetic than visible light.

1. Absorbs blue, violet and red spectrums, reflects green rays.

2. The coverage of the green spectrum, to see more green tones.

3. Electromagnetic waves such as light do not interfere with each other’s path, it is one of the basic rules.

4. See 3.

5. Between red and violet.

6. Human eyes adapted to see in the light, as we don’t live underwater and have no need to see at night.

7. The only thing that changes between them is the frequency, both are electromagnetic.

8. Heat.

9. Heat.

10. All electromagnetic.

11. The more dense, the less it refracts.

12. Going through different densities.

13. Refraction.

14. Real, inverted and smaller. Between F and C.

15. Real, inverted and bigger. Before C.

16. Range of colors dispersed by white light. First used for the rainbow.

17. Reflection.

Answer: 0.0045 mol
Explanation: Convert 30 ml to l: 30 mL = 0.03 L
Molarity = mol/l
mol = molarity * L
mol = 0.15 * 0.03 = 0.0045 mol
Answer: 0.0045 mol
Explanation: Convert 30 ml to l: 30 mL = 0.03 L
Molarity = mol/l
mol = molarit

Answer: chalcogens.
Explanation: Strontium is an alkaline earth metal, it always exhibits a degree of oxidation in its compounds +2.
Chalcogens are a group of 6 chemical elements (oxygen O, sulfur S, selenium se, tellurium te, polonium Po) that have an oxidation state of -2 => Chalcogens will combine with strontium in a ratio of 1:1.

Answer:

52.6 gram

Step-by-step explanation:

It is clear by the equation 2(27+3×35.5)= 267 gm of AlCl3 reacts with 6× 80 = 480 gm of Br2 . So 29.2 gm reacts = 480× 29.2/267= 52.6 gm
