<h3>Answer:</h3>

Vacuum

<h3>Explanation:</h3>

Concept being tested: Waves and types of waves

To answer the question we need to define both electromagnetic waves and mechanical waves.

  • Waves can be classified as either electromagnetic waves and mechanical waves based on whether they require a material medium for transmission or not.
  • Electromagnetic waves do not require a material medium for transmission and can travel through a vacuum.
  • Mechanical waves, on the other hand, are waves that require a material medium for transmission.

What are examples of electromagnetic waves and mechanical waves?

  • Examples of electromagnetic waves include gamma rays, radio waves, visible light, etc.
  • Examples of mechanical waves include sound waves and water waves.

Therefore, the answer to our question is;

  • Electromagnetic waves are not mechanical waves, which means they can travel in a vacuum.

If 710- nm and 660- nm light passes through two slits 0.65 mm apart, how far apart are the second-order fringes for these two wa
alexira [117]

0.23 mm far apart are the second-order fringes for these two wavelengths on a screen 1.5 m away.

<h3>Given wavelengths 710nm and 660nm,0.65mm apart two slits, and a screen 1.5m away.</h3>

Position of n the order fringe = n λ D / d

for n = 2

position = 2 λ D / d

λ = 710 nm , D = 1.5m

d = .65 x 10⁻³

position 1 = 2 x 710 x 10⁻⁹ x 1.5 / .65 x 10⁻³

= 3276.92 x 10⁻⁶ m

= 3.276x 10⁻³ m

= 3.276mm .

For λ = 660 nm

position = 2 λ D / d

λ = 660 nm , D = 1.5 m

d = .65 x 10⁻³

position 2 = 2 x 660 x 10⁻⁹ x 1.5 / .65 x 10⁻³

= 3046.15 x 10⁻⁶ m

= 3.046 x 10⁻³ m

= 3.046 mm .

Difference between their position

= 3.276mm ₋ 3.046 mm

= 0.23 mm .
