Quick Answer: What is the wavelength of light having a frequency of 4.8 × 1014 s–1 (c = 3.00 × 108 m/s)?

What is the wavelength of light having a frequency of 4.8 x10 14?

c = fλ (3 x 108 m/s) = ( 4.8 x 10 14 Hz)λ λ = 6.25 x 107 m This is orange light!

What is the wavelength of light with a frequency of?

Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz. The EM spectrum.

Type of Radiation Frequency Range (Hz) Wavelength Range
radio waves < 3*1011 > 1 mm

How do you find a wavelength?

Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda λ, so λ = v/f.

What is the wavelength in units of meters?

In an equation, wavelength is represented by the Greek letter lambda (λ). Depending on the type of wave, wavelength can be measured in meters, centimeters, or nanometers (1 m = 109 nm ). The frequency, represented by the Greek letter nu (ν), is the number of waves that pass a certain point in a specified amount of time.

Which light has longest wavelength?

Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400.

What is the wavelength of normal light?

Visible light is usually defined as having wavelengths in the range of 400– 700 nm, or 4.00 × 107 to 7.00 × 107 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).

What is the frequency of visible light in Hz?

Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 1014 to 8 × 1014 cycles per second, or hertz (Hz ) and wavelengths of about 740 nanometers (nm) or 2.9 × 105 inches, to 380 nm (1.5 × 105 inches).

What is wavelength equal to?

Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f.

How long is 1 wavelength?

Frequency – Wavelength Chart

Frequency Wavelength 1/100 Wavelength
1 MHz 300 meters 3 meters
10 MHz 30 meters 30 cm
50 MHZ 6.0 meters 6.0 cm
100 MHz 3.0 meters 3.0 cm

What is a wavelength measured in?

Wavelength is usually measured in meters (m). Frequency is the number of cycles of a wave to pass some point in a second. The units of frequency are thus cycles per second, or Hertz (Hz).

What is wavelength and its units?

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave. Since wavelength is distance/length, it is measured in units of lengths such as metres, centimetres, milimetres, nanometres, etc.

What is the wavelength of the wave the unit is CM?

A centimeter (cm ) is a decimal fraction of the SI unit of wavelength meter. Example: Microwaves typically have frequencies 0.3 to 300 GHz (100 cm to 1 mm). A microwave oven works usually at a frequency of 2.45 gigahertz (GHz)—a wavelength of 12.2 centimeters.
