7.5 x 10⁻¹¹m. An electromagnetic wave of frecuency 4.0 x 10¹⁸Hz has a wavelength of 7.5 x 10⁻¹¹m.

Wavelength is the distance traveled by a periodic disturbance that propagates through a medium in a certain time interval. The wavelength, also known as the space period, is the inverse of the frequency. The wavelength is usually represented by the Greek letter λ.

λ = v/f. Where v is the speed of propagation of the wave, and "f" is the frequency.

An electromagnetic wave has a frecuency of 4.0 x 10 ¹⁸Hz and the speed of light is 3.0 x 10⁸ m/s. So:

λ = (3.0 x 10⁸ m/s)/(4.0 x 10¹⁸ Hz)

λ = 7.5 x 10⁻¹¹m

The eyepiece of a compound telescope has a focal length of 12 cm and the objective lens has a focal length of 16 m. What is the
olasank [31]

Answer:

The magnification is 133X

Explanation:

For a refractor telescope using convex lenses, the overall magnification os calculated as by dividing the focal length of the objective by that  of the eyepiece.

M = \frac{f(obj)}{f(eye)}

So:

M = \frac{16 m}{12 cm}

Care must be taken with the units, in this case they are in meters and centimeters, they should be converted into the same unit before calculating:

M = \frac{16 m}{0.12 m} = 133

What cell processes occour during interphase
Feliz [49]
The cell cycle has two main phases, interphase and mitosis. Mitosis is the process during which one cell divides into two. Interphase is the time during which preparations for mitosis are made. Interphase itself is made up of three phases -- G1 phase, S phase, and G2 phase -- along with a special phase called G0.
